Engineered for residential and commercial applications, the 25A single-pole breaker provides standard overload and short-circuit protection. It installs into Eaton and Cutler-Hammer Type CH load centers utilizing a 3/4-inch per pole footprint. Featuring a 10kAIC rating at 120/240V, this HACR-rated unit accommodates 14-8 AWG copper or aluminum wiring.

Product FAQs

6 answers
What panels are compatible with the CH125 circuit breaker?

This breaker is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It requires one 3/4-inch space on the busbar.

Can I install a CH125 in an Eaton Type BR load center?

No. Type CH breakers have a 3/4-inch width per pole, while Type BR breakers are 1 inch wide. They use different mounting mechanisms and are not interchangeable.

Is the CH125 suitable for HVAC equipment?

Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration applications that require a 25A overcurrent protection device.

What is the difference between the CH125 and the CHF125?

The CHF125 is the updated version of the CH125. The primary difference is that the CHF series includes a mechanical trip flag indicator to easily distinguish a tripped state from the off position. Both fit the same Type CH panels.

Are Eaton CH125 and Cutler-Hammer CH125 the same breaker?

Yes. Eaton acquired Cutler-Hammer, and the CH125 part number remains identical. They are the exact same breaker and are fully interchangeable in Type CH panels.

What is the recommended terminal torque for the CH125?

Always verify the exact torque specifications on the breaker label or load center publication. Generally, Eaton CH breakers require 20 lb-in of torque for 14 to 10 AWG wire connections.

    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!
