Best Circuit Breaker Brands: Square D, Eaton, Siemens & More

Introduction: Why Circuit Breaker Brand Matters

Circuit breakers are the guardians of electrical safety in our homes, commercial buildings, and industrial facilities. Choosing a reliable, well-engineered breaker is crucial – these devices protect against overloads, short circuits, and electrical faults that could otherwise cause fires or equipment damage. The brand of circuit breaker does matter: a breaker’s quality and longevity are often tied to its manufacturer. Top brands invest in rigorous testing and innovation to meet industry standards, ensuring their breakers trip when needed and stay dependable for decades. In this circuit breaker comparison, we will examine leading brands like Square D, Eaton, and Siemens (among others) to see how they stack up in terms of reliability, performance, and value.

Equally important is compatibility. Most circuit breaker panels are designed for a specific brand of breaker, and mixing brands can be unsafe or even a code violation. Unless a breaker is classified for use in another manufacturer’s panel, you should stick to using the same brand breakers as the panel to ensure proper fit and performance. With that in mind, let’s explore the best circuit breaker brands – both for residential circuit breakers and industrial circuit breakers – and what makes each stand out.

Square D (Schneider Electric) Circuit Breakers

Square D (a flagship brand of Schneider Electric) is often considered one of the best circuit breaker brands, highly regarded by electricians and contractors. Square D breakers are ubiquitous in North America, used in everything from home electrical panels to large industrial switchgear. The brand’s reputation comes from a long history of quality and innovation. For example, Square D’s popular QO series breakers have a patented Visi-Trip indicator (a small window that shows red when the breaker has tripped), making it easy to identify a tripped circuit. The QO line (“Quick Open”) is known for its fast response to faults and solid construction – so much so that many professionals won’t hesitate to recommend Square D for critical applications.

Residential vs. Industrial: Square D offers solutions across the spectrum. In homes and light commercial settings, Square D’s QO and Homeline breakers are common in load centers and panelboards, prized for their reliability. In the industrial realm, Schneider Electric produces high-performance breakers under the Square D name (such as the PowerPact and MasterPact series) that handle higher voltages and currents. These industrial breakers come with advanced features like electronic trip units and remote monitoring capabilities for facility management. Square D breakers might come at a slightly higher price point than some competitors, but they deliver excellent build quality and longevity – a true case of getting what you pay for in terms of reliability and performance.

Notable Features: Many Square D products carry a limited lifetime warranty, reflecting the manufacturer’s confidence in their longevity. The brand has also kept pace with technology: Square D was among the first to introduce smart breakers and energy-monitoring panels for homes. Overall, Square D is a top choice when you need peace of mind that your breaker will perform when it counts, whether in a residential fuse box or a factory distribution board.

Eaton (Cutler-Hammer) Circuit Breakers

Eaton is another industry giant, offering a broad range of circuit breakers for residential, commercial, and industrial applications. Eaton’s portfolio includes the legacy Cutler-Hammer line – a brand with roots back to 1892 that became part of Eaton in 1978. You’ll often see Eaton and Cutler-Hammer mentioned together because Eaton continues to use the Cutler-Hammer name for many of its breaker products (for example, “Eaton / Cutler-Hammer” breakers). This brand family is known for innovation and wide usage: Cutler-Hammer was an early pioneer in safety breakers, introducing technologies like the “FireGuard” arc-fault circuit breaker to help prevent electrical fires.

Residential vs. Industrial: In residential settings, Eaton breakers are very common – especially the Cutler-Hammer CH series (with distinctive tan-colored handles) and the BR series. These breakers are valued for being solid and cost-effective choices for home electrical panels. Many electricians choose Eaton breakers for panel upgrades because they strike a good balance of reliability and price. On the industrial side, Eaton manufactures heavy-duty circuit protection devices, including molded case breakers up to high current ratings and even large air circuit breakers for switchgear. After acquiring brands like Westinghouse’s breaker division in the 1990s, Eaton ensured that many older systems could be supported with new breakers under the Eaton/Cutler-Hammer umbrella. This means if you have an older Westinghouse or Cutler-Hammer panel, Eaton likely has a direct replacement breaker available – a big plus for maintainability.

Notable Features: Eaton offers both thermal-magnetic breakers for standard protection and more sophisticated electronic trip breakers for advanced coordination and monitoring. A standout feature in Eaton’s residential lineup is the “CH” series breaker’s premium construction and lifetime warranty, which many professionals trust for long-term installations. Eaton also produces classified breakers – devices tested to be cross-compatible in other brands’ panels (useful when an exact brand breaker isn’t available). However, you should only use these if they are UL-listed as compatible replacements. Overall, Eaton’s breadth of products and history of absorbing other brands make it a versatile and reliable choice for both homes and industry.

Siemens Circuit Breakers

Siemens is a global leader in electrical engineering, and its circuit breakers are widely used around the world. In the United States, Siemens breakers (and panels) gained prominence after Siemens acquired ITE (Industrial Technology Electrical) in 1983. Siemens continued to produce ITE-designed breakers for years under the Siemens/ITE names, and today it sells all those breakers simply under the Siemens brand. This means if you encounter older ITE or Gould breakers, the modern equivalents are likely Siemens products.

Residential vs. Industrial: Siemens breakers are very popular in residential service panels – many builders and electricians favor Siemens load centers for their combination of quality and affordability. In fact, Siemens panels and their QP series breakers are often found at home improvement stores as a dependable option for home electrical projects. Siemens residential breakers are typically thermal-magnetic type, similar in performance to Eaton and Square D Homeline breakers, with standard features like plug-on neutral designs for easier installation of GFCI/AFCI breakers. For industrial and commercial applications, Siemens offers an expansive range: from molded case breakers in distribution panels to large air circuit breakers and vacuum circuit breakers for medium-voltage systems. The company’s industrial breakers are known for robust construction and high interrupting ratings, capable of protecting heavy machinery and complex electrical networks.

Innovation and Features: Siemens has a strong reputation for innovation in circuit protection. For example, Siemens was one of the first to introduce a breaker that combined both arc-fault and ground-fault protection in a single device (a “dual function” AFCI/GFCI breaker) – an innovation that was recognized as a top product at the 2014 NECA industry conference. Siemens also develops smart power management features; their breakers can be integrated into building management systems for remote status monitoring and control. Like other top brands, Siemens breakers meet stringent UL standards and are built for reliability. They might not have a flashy reputation in the consumer market, but among professionals, Siemens is seen as a solid, high-performance brand. Many also appreciate that Siemens breakers are widely available and sometimes interchangeable (physically) with other panel brands – though, again, official guidance is to use the proper listed breaker for the panel for safety.

General Electric (GE) and ABB Circuit Breakers

General Electric (GE) has long been a household name in electrical equipment, and its circuit breakers have been among the most used in North America. GE breakers can be found in many older homes and industrial facilities; the brand built a wide range of breaker types for low, medium, and high voltage applications. GE’s residential breakers (e.g., the THQL series) were known for being reliable and widely stocked, making them a go-to for electricians doing repairs or upgrades in legacy GE load centers. In the industrial sphere, GE developed breakers like the Spectra and EntelliGuard series, emphasizing innovation in safety and monitoring. For instance, GE introduced the GuardEon molded-case circuit breaker line in 2016 with features to monitor the breaker’s mechanical and electrical health, helping facilities predict maintenance needs. This focus on advanced trip units and health monitoring (through technologies like GE’s ArcWatch and Trip Unit Toolkit software) set GE’s offerings apart for high-end applications where uptime is critical.

In 2018, ABB (a Swiss-Swedish engineering conglomerate) acquired GE’s Industrial Solutions division. ABB itself is one of the top circuit breaker manufacturers globally, known especially in Europe and Asia for high-quality breakers and switchgear. Through the acquisition, ABB absorbed GE’s breaker product lines and customer base. Today ABB produces breakers that serve as direct replacements for legacy GE models (for example, the ABB Tmax XT series now covers the range once served by GE’s Spectra breakers). ABB’s name might not have been as common in everyday U.S. residential wiring in the past, but it’s a powerhouse in the industrial electrical market worldwide. ABB breakers are praised for their engineering excellence and are often used in critical power systems, renewable energy installations, and other demanding environments. In some regions, you’ll see ABB breakers more frequently than U.S.-centric brands.

GE vs. ABB – What’s the difference now? Essentially, GE’s breaker designs live on under ABB’s portfolio. If you have a GE panel, you can still find the appropriate breakers – they might be labeled as GE (for continuity) or ABB, but they come from the same lineage. Both brands stand for reliability. GE’s long history in the U.S. means a huge installed base (and many electricians are familiar with their products), while ABB’s global reach brings in cutting-edge technology and a reputation for industrial-grade performance. Together, they cover everything from a simple 20-amp house breaker to oversized breakers for factory substations.

Other Notable Brands and Considerations

The electrical industry includes other breaker brands like Mitsubishi Electric, Schneider Electric (global), Federal Pacific (FPE), Challenger, Zinsco, and more. Some of these names pop up in specific niches or older installations. For instance, Federal Pacific and Zinsco breakers are found in many pre-1980s homes but are no longer made (and in fact, FPE Stab-Lok breakers are infamous for safety issues). Challenger was acquired by Eaton, and its panels often use Eaton replacement breakers now. Mitsubishi and Alstom have provided specialized high-voltage breakers for industrial and utility use. Schneider Electric, as the parent of Square D, also sells breakers globally under brands like Merlin Gerin. When dealing with an existing electrical system, it’s important to identify the original panel brand and source compatible breakers accordingly. The “big five” brands we discussed – Square D, Eaton (Cutler-Hammer), Siemens, GE, and ABB – cover the vast majority of needs in the North American market for new and replacement breakers.

Regional availability can play a role as well. In some parts of the world, you’ll see certain brands dominate due to local standards and distribution. For example, in Europe one might encounter more ABB, Schneider, or Siemens, whereas in the United States, Square D, Siemens, Eaton/CH, and GE are more familiar names. Ultimately, all top manufacturers have to meet similar safety certifications (UL, IEC, etc.), so the “best” brand may come down to what fits your system, your budget, and your feature requirements.

Residential vs. Industrial Circuit Breakers

It’s important to distinguish between the breakers used in a home electrical panel and those used in a large industrial setting. While their core function is the same – automatically interrupting power when there’s an overload or fault – the design, capacity, and features of residential vs. industrial circuit breakers can be very different.

Capacity and Size: Residential circuit breakers are typically rated for lower voltages (120/240V in North America) and moderate current levels (15A to 200A for typical home main panels). They are usually compact, plug-in style breakers to fit standardized home panels. Industrial circuit breakers, on the other hand, often handle much higher voltages and currents – from 480V systems in commercial buildings up to many kilovolts in factories and utility substations. These breakers are physically larger and built to endure heavy-duty conditions. In fact, industrial breakers are often physically bolted in or draw-out mounted in switchgear assemblies, rather than simply plugged in.

Complexity and Features: A standard residential breaker is a simple thermal-magnetic device – it has a bimetal strip and maybe a magnetic coil for instantaneous trip, and it’s largely self-contained and maintenance-free. Industrial circuit breakers are much more complicated than residential versions and can handle far more voltage. Industrial breakers come in many types (molded case, insulated case, air circuit breakers, vacuum breakers, etc.), each with various operating mechanisms and arc extinguishing methods (some use air, some use vacuum bottles, SF₆ gas, etc.). They often have adjustable trip settings, interchangeable trip units, remote operation capability, and need periodic testing. This complexity is necessary because industrial systems may require coordination between multiple breakers, precise trip curves to protect sensitive equipment, or networked communication for monitoring. As a result, selecting an industrial breaker usually involves an engineer or specialist to ensure the breaker’s specs (interrupting rating, trip unit settings, frame size, etc.) match the application’s needs.

Reliability and Standards: Both residential and industrial breakers are subject to rigorous standards (UL 489 for most molded-case breakers, UL 1077 for supplementary protectors, ANSI/IEEE standards for high voltage breakers, etc.). However, industrial breakers often have higher interrupting ratings (the ability to safely clear a short-circuit current). For example, a typical home breaker might interrupt 10,000 AIC (Amps Interrupting Capacity), whereas an industrial breaker might handle 65,000 AIC or more, and medium-voltage breakers in a substation can break tens of thousands of amps at very high voltages. The stakes are higher in industrial settings – a breaker failure at a factory can mean costly downtime or dangerous arc-flash incidents – so these breakers are built and tested to extremely high reliability standards.

Maintenance Differences: We’ll discuss maintenance more below, but it’s worth noting that residential breakers are generally maintenance-free aside from an occasional exercise or making sure connections remain tight. Industrial breakers, by contrast, often have maintenance schedules – including regular inspections, cleaning, lubrication of mechanisms, and testing of trip functions. For instance, a low-voltage power circuit breaker (LVPCB) in a factory might be inspected and serviced every year or two, whereas a house breaker might quietly do its job for 30 years with no intervention beyond resetting it after a trip.

In summary, residential breakers are designed for simplicity and ease of use, while industrial breakers are engineered for performance and adaptability to complex electrical environments. Knowing the difference is important – you wouldn’t use a tiny residential breaker to protect a large motor circuit, and conversely using an oversized industrial breaker in a home panel would be impractical (and likely not code-compliant). Choose the right type for the job: homes typically need reliable, simple breakers, whereas industrial projects demand robust units tailored to their specific electrical loads.

Reliability, Performance, and Cost Considerations

All the top circuit breaker brands we’ve discussed have a strong baseline of reliability – they have to, in order to meet safety codes and earn the trust of electricians. However, there are some nuances in performance and cost that may influence which brand or breaker model you choose:

• Baseline Quality: A breaker’s job is critical, so reputable manufacturers build them to perform under stress. A breaker should trip within milliseconds during a short-circuit and endure thousands of on-off cycles over its life. Cutting corners on quality is dangerous, so sticking with a reputable brand is key. The major brands (Square D, Eaton, Siemens, GE/ABB) have decades of engineering behind them, and their breakers are tested to handle real-world conditions. That said, even the best breaker can fail if it’s a counterfeit or if it’s misapplied – another reason to purchase through trusted suppliers and ensure compatibility.
• Performance Features: Some brands offer specialized performance features. For example, certain Square D and Siemens breakers employ electronic trip units that can be finely tuned or that communicate status to an external system. These are usually found in larger frame breakers for commercial/industrial use. If your project requires adjustable trip settings, remote monitoring, or integration into energy management systems, you might lean toward the specific product line (and thus brand) that offers those features. In terms of interruption performance, check the AIC rating of the breaker – all brands make standard duty breakers (e.g., 10kA or 22kA for small ones) and higher-rated ones (65kA, 100kA) for networks with higher fault currents. Ensure the breaker you select has a rating equal or above the available fault current in your system, regardless of brand.
• Cost and Value: There can be cost differences between brands and between product lines of the same brand. From a broad perspective, Square D and Siemens breakers are often considered mid-to-premium in price; Eaton (Cutler-Hammer) and GE breakers are sometimes seen as very cost-effective options for standard residential needs. For instance, if you’re outfitting a basic residential panel, a solid but budget-friendly GE or Eaton breaker line will do the job well. On the other hand, if you need “feature-rich” breakers with advanced electronics, you might be looking at an ABB or Schneider Electric (Square D) solution that comes at a higher price. It’s worth noting that within each brand, there may be a budget line and a premium line: Square D’s Homeline breakers are more economical than their QO series; Eaton’s BR series is slightly cheaper than CH series; Siemens has value packs aimed at contractors. When considering cost, also factor in availability – a more expensive breaker that’s readily available might be preferable to a cheaper one that’s back-ordered for weeks (a consideration that has become prominent with recent supply chain fluctuations).
• Compatibility and Existing Infrastructure: Sometimes the “best” brand for you is dictated by what you already have. If your facility or project has standardized on a brand (for example, all your panels are Square D or all your switchgear is Siemens), sticking with that brand can simplify maintenance and spare parts inventory. All the top brands provide broad product support, but mixing different systems can introduce complexity. Many facility managers choose one or two brands to work with consistently so that breakers, mounting hardware, and even accessory parts (like auxiliary switches or trip units) are interchangeable within their inventory.
• Support and Warranty: Top manufacturers typically offer good customer support and warranties. Square D and Eaton often provide long warranties on their residential breakers (sometimes lifetime for original owner). Industrial breakers usually come with robust support – including technical hotlines, field service technicians, and authorized repair centers for things like retrofitting or reconditioning breakers. Consider the level of support you might need. In an industrial context, having a manufacturer that offers on-site service or quick turnaround on replacements can be a big plus.

In essence, all major brands will deliver on core safety and performance, but your specific needs will determine which brand is “best”. If you need the cheapest safe option to get a job done in a small building, an Eaton/CH or GE breaker might be ideal. If you require top-of-the-line features or have existing brand loyalty, Square D, Siemens, or ABB might be the choice. Take a close look at specifications, and when in doubt, consult with an electrical supplier or engineer who can provide a circuit breaker comparison tailored to your scenario.

Circuit Breaker Maintenance and Lifespan

Buying a good breaker is only part of the equation – maintaining it is key to extend circuit breaker life and ensure it will operate correctly in the long run. A circuit breaker can only protect your system if it functions properly at the moment of truth. Fortunately, breakers are generally very durable. Many industrial circuit breakers are designed to last for decades, and in typical environments a breaker might function for 30+ years. In fact, Schneider Electric (maker of Square D) notes that the expected life of a molded-case circuit breaker is about 30 years given a favorable environment and regular maintenance. However, poor conditions or lack of upkeep can shorten that lifespan.

Here are some maintenance tips to increase breaker lifespan and keep your electrical system safe:

• Keep it Clean: Dust, dirt, and moisture are the enemies of electrical equipment. Simply keeping breakers and panels clean can prevent a lot of problems. Accumulated dust can cause overheating or interfere with the breaker mechanism. Wipe down panels periodically and ensure no debris or corrosion is building up on the breakers. If a breaker is in a harsh environment (like a factory floor with lots of dust or a damp location), consider using NEMA-rated enclosures or special protective covers to shield it from contaminants.
• Monitor the Environment: Excessive heat and humidity can degrade breaker components over time. Ensure that your electrical rooms are cool and dry. If a breaker panel is in a space that regularly exceeds the normal temperature range (for example, near a furnace or in direct sun in an attic), you might need ventilation or cooling to avoid heat fatigue on the breakers. Likewise, very cold environments can stiffen lubrication. Aim for a stable, moderate environment for critical breakers. Industrial facilities often install temperature and humidity monitors in electrical rooms to get early warning of unfavorable conditions.
• Exercise the Breakers: One commonly overlooked aspect of circuit breaker maintenance is simply exercising the mechanical parts. Breakers can seize up if they never operate. It’s recommended to cycle each breaker OFF and ON at least once a year (and press the “Test” or trip button if it has one). This practice, often called “annual exercising,” ensures the moving parts and spring mechanisms don’t get stuck from disuse. Both Schneider Electric and other experts note that annual on-off cycling helps keep the breaker mechanism operable for the long term. After cycling, reset the breaker to ON and you’re good to go. Always warn anyone affected by the outage, and only do this if it’s safe to interrupt power briefly.
• Regular Testing: In addition to manual exercising, critical breakers should be electrically tested on a routine schedule. For residential breakers, this might simply mean using the test button on GFCI/AFCI breakers monthly (as recommended) to ensure those safety functions work. In industrial settings, routine trip testing every 3-5 years is advised. This can involve injecting a test current to verify the breaker trips at the set threshold or using specialized equipment to simulate fault conditions. Such testing is often done by licensed professionals, especially for high-voltage or complex systems. The goal is to catch any calibration drift or mechanical issue before a real fault happens.
• Inspection and Servicing: Particularly for large breakers, schedule a detailed inspection at least every few years. This may include checking the tightness of connections (loose lugs cause heat), looking for signs of overheating or wear, cleaning and re-greasing pivot points per the manufacturer’s guidelines, and testing any auxiliary components (like shunt trips or alarm contacts). Industrial breaker maintenance schedules often follow standards such as NETA MTS or manufacturer manuals, which might specify inspections at 1-year, 3-year, 5-year intervals with increasing scope. As a rule of thumb, more frequent maintenance is needed if the breaker is in a harsh environment (dusty, corrosive, etc.), if it’s an older unit, or if it experiences frequent switching operations or trips.

By performing this kind of circuit breaker maintenance, facilities can significantly extend the service life of their breakers and keep them operating safely. It’s far cheaper to clean and tighten a breaker annually than to deal with the fallout of a breaker that failed to trip in an emergency. Remember, a healthy breaker is one of the last lines of defense against electrical disasters.

Lastly, always follow safety protocols during maintenance – only qualified individuals should open live panels or test breakers, and proper PPE (Personal Protective Equipment) for electrical work is a must due to arc flash risk. If you’re unsure how to proceed with maintaining a critical breaker, consult the manufacturer’s guidelines or hire a certified breaker service technician. With care and attention, you can increase breaker lifespan to match (or even exceed) the manufacturer’s expectations, keeping your electrical system running smoothly for years to come.

FAQ: Common Questions about Circuit Breaker Brands

Q: What is the best circuit breaker brand?

A: There isn’t a single “best” brand for all situations – several top brands are known for reliability. Square D, Eaton (Cutler-Hammer), Siemens, ABB, and GE are all highly regarded. Each has its strengths: for instance, Square D is often praised by electricians for quality, while Eaton/CH and GE breakers are known to be dependable and budget-friendly for home use. The best choice depends on your specific needs (residential vs. industrial, any brand-specific panel requirements, desired features). All the major brands meet strict safety standards, so focus on finding the right type and model for your application. If you stick to these reputable manufacturers, you can be confident in the breaker’s performance.

Q: Can I mix different brands of breakers in the same panel?

A: Generally no – you should not mix brands in a panel unless the breaker is explicitly classified for that panel. Circuit breaker panels are designed, tested, and UL-listed with specific breaker models. Inserting a breaker of a different brand or type that isn’t listed for that panel can be unsafe and violate electrical codes. While some breakers might physically “fit” in another brand’s panel, it’s not recommended because the connection and trip characteristics might not be compatible. The only time it’s acceptable is if a breaker is labeled as a UL Classified Replacement for another brand (for example, Eaton makes some breakers that are classified to replace certain Square D or Siemens breakers in their panels). Always check the panel’s documentation or labeling – it will specify which breaker types are allowed. When in doubt, use the same brand of breaker as the panel, or consult with an electrician.

Q: How long do circuit breakers last?

A: Circuit breakers are built to last a long time. The average lifespan often quoted is around 30 to 40 years for molded-case breakers (like those in home panels) under normal conditions. Schneider Electric advises about a 30-year life expectancy for MCCBs, assuming a clean environment and regular maintenance. Many breakers in service today have been working for decades. However, lifespan can vary: high-use or harsh environments might age a breaker faster, whereas a lightly loaded breaker in a clean, climate-controlled setting could function far beyond 40 years. It’s important to note that breakers don’t have moving parts that wear out in normal operation (unless they trip frequently). The factors that often limit a breaker’s life are insulation breakdown, corrosion, or mechanical seizing due to lack of use – all of which are mitigated by proper maintenance. Always replace a breaker if it shows signs of damage, overheating (scorch marks, melted parts), or if it becomes mechanically difficult to switch on/off.

Q: How can I extend the life of my circuit breakers?

A: The key to a long breaker life is proper maintenance and operating conditions. Keep your breaker panel clean and free of dust. Ensure the area isn’t exposed to extreme heat, moisture, or corrosive vapors. It’s a good practice to exercise breakers annually – simply flip them off and back on (and use the test button on any GFCI/AFCI breakers) to keep the internal mechanism from sticking. For industrial breakers, adhere to a maintenance schedule: periodic inspections, cleaning, lubrication of moving parts, and testing of trip functions will all help. If a breaker trips due to a fault, don’t repeatedly reset it without investigating the cause – frequent tripping can stress a breaker, so find and fix the underlying issue. By treating breakers well – much like any critical equipment – you can extend circuit breaker life and ensure they reliably protect your system when needed.

Q: What’s the difference between residential and industrial circuit breakers?

A: The main differences are capacity, construction, and features. Residential breakers are smaller, typically rated for 120/240V circuits, and are usually plug-in style for ease of use in home panels. They handle moderate currents (15A-200A) and have fixed thermal-magnetic trip settings appropriate for home wiring. Industrial breakers, by contrast, can handle much higher voltages (480V, 600V, or far higher for medium-voltage systems) and currents (hundreds to thousands of amps). They are built tougher – often with bolt-on or draw-out metal frames – and may use advanced methods to extinguish arcs (like air blast, vacuum chambers, or SF₆ gas). Industrial breakers often have adjustable trips or electronic trip units, allowing engineers to set precise protection settings. They also might feature remote control or monitoring, something unnecessary for home breakers. In short, residential breakers are simple and standardized, whereas industrial breakers come in many types tailored to specific high-power applications. They both prevent overloads and short circuits, but an industrial breaker is to a home breaker what a heavy-duty truck is to a passenger car – built for much more demanding work.

By understanding the strengths of each brand and the needs of your electrical system, you can choose circuit breakers that will provide safe, reliable service for years to come.
