The new surplus THJK436225 arrived in perfect condition just as it was described. Professionally packaged in pristine condition. Couldn't ask for more.

Good choice!!

This is the second time we have purchased from Breaker Hunter, and both times the Circuit Breaker arrived in better condition than I expected. Good service

Nice Surprise

I was skeptical at first, they had the breaker I needed, priced fairly, and it shipped timely, well packaged, perfect condition (new). I give them an A+.
