- CSChristine S.Verified BuyerReviewingEaton / Cutler-Hammer CH2100-LONG - 100A 2 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars5/18/26Got a great refurbished breaker - saved a $6500 Service Replacement
When our main breaker frizzed out, the option we were presented with was replacing the entire panel and service due to the type and part - no longer produced for replacement parts. It would be a $6500 replacement.
We'll likely have to do it at some point but, for now, the replacement breaker we were able to source from Superbreakers (with a $25 warranty) was $5900 less expensive. installation ran a few hundred dollars and the tech said the part looked to be in excellent condition and was prepped for install as he would have hoped.
Very thankful for SuperBreakers!
