Product FAQs
4 answersCan the CH250SUR be installed in standard BR series panels?
No. The CH250SUR is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It utilizes a specific plug-on mounting design that is not physically compatible with Type BR or other manufacturer panels.
What does the "SUR" suffix indicate on the CH250SUR catalog number?
The "SUR" suffix designates this unit as a Surge Protective Circuit Breaker. It combines standard 50A branch overcurrent protection with integrated surge protection for the load center in a single device.
How should wiring be terminated on the CH250SUR?
Wiring should be terminated using the integrated box lugs, which accept 14 AWG to 6 AWG copper or aluminum conductors. Always verify that the selected wire gauge meets local electrical codes for a 50A circuit.
How does the thermal-magnetic trip mechanism function on this breaker?
The thermal-magnetic design provides dual protection. The thermal component offers a long-time delay to prevent nuisance tripping on mild overloads, while the magnetic component provides an instantaneous trip response to safely clear severe short circuits.

- 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!
