Product FAQs

7 answers
What panelboards are compatible with the CHB230 circuit breaker?

This breaker mounts directly into Cutler-Hammer Type PB panelboards, Type PH panelboards, and compatible Eaton meter panels. It requires a bolt-on connection and will not fit standard plug-on load centers.

What is the difference between Eaton CH and CHB circuit breakers?

Both series feature a 3/4-inch width per pole, but they utilize different mounting methods. Type CH breakers are plug-on variants designed for residential load centers, whereas Type CHB breakers are bolt-on variants engineered for commercial panelboards.

Is the CHB230 breaker HACR rated?

Yes, this 30-amp thermal magnetic breaker is HACR rated. This certifies it for use with heating, air conditioning, and refrigeration equipment that requires multi-motor branch circuit protection.

What wire type and gauge do the CHB230 terminals accept?

The built-in box lug terminals are approved for either copper or aluminum conductors ranging from 14 AWG to 8 AWG.

How do you reset a tripped CHB230 breaker?

When a fault occurs, the handle on a Type CHB breaker trips to a middle position between ON and OFF. To restore power, you must manually push the handle to the full OFF position to reset the internal mechanism before switching it back to ON.

Can I interchange a CHB230 with a BAB2030 circuit breaker?

No. While both are 30-amp, 2-pole bolt-on breakers, they have different physical dimensions and fit different chassis. The CHB230 is 3/4-inch wide per pole, while BAB breakers are 1-inch wide per pole. They are not interchangeable.

Are Cutler-Hammer and Eaton CHB breakers the same?

Yes. Eaton acquired the Cutler-Hammer brand and continues to manufacture the CHB series. A modern Eaton CHB230 is a direct, UL listed replacement for older Cutler-Hammer branded breakers with the exact same catalog number.

    Was what I needed

    This breaker was exactly what I needed. I did not give it 5 starts because it was SUPER expensive for this frame size breaker.
