My plant was down and I needed a breaker ASAP after a diligent search we found one. We opted for rush service and our plant was back in operation the next day. Money well spent.

The team at Breaker Hunters was a huge help. They had what I needed in stock and hundreds of dollars cheaper than anywhere else I could find. Would highly recommend them to anyone looking for electrical items!

Great, however the box weighed more than the breaker. Twenty eight dollars shipping and handling was a bit much. Thanks Jack
