Product FAQs

7 answers
How much space does the CH350 require in a panel?

The CH350 is a 3-pole breaker that requires three standard 3/4-inch spaces, occupying a total width of 2.25 inches on the bus bar.

Which load centers accept the CH350 circuit breaker?

This breaker is designed specifically for Eaton and Cutler-Hammer Type CH load centers. It will not fit in Type BR (1-inch) panels or load centers from other manufacturers.

Will this Eaton breaker fit in an older panel labeled Cutler-Hammer?

Yes. Eaton acquired Cutler-Hammer, and current Eaton Type CH breakers are directly backward compatible with legacy Cutler-Hammer Type CH load centers.

Does the CH350 feature a common trip mechanism?

Yes, the breaker has an internal common trip connection. If a fault occurs on any single phase, all three poles will open simultaneously to completely disconnect power.

What is the trip position for Eaton CH standard breakers?

Unlike breakers that trip to a center position, standard Type CH circuit breakers trip fully to the OFF position, making it clear when the circuit has tripped and needs to be reset.

How can I visually identify a standard Type CH breaker for replacement?

Standard Eaton and legacy Cutler-Hammer Type CH breakers are easily recognizable by their 3/4-inch per pole width and signature Sandalwood (light tan) toggle handles.

Is the CH350 suitable for use with HVAC equipment?

Yes, this breaker is HACR (Heating, Air Conditioning, and Refrigeration) rated, making it code-compliant for HVAC applications requiring a 50A, 3-pole breaker.

    Got 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!
