Product FAQs

6 answers
Which panelboards are compatible with the CHB3100 circuit breaker?

This bolt-on breaker is designed for use in Eaton and Cutler-Hammer Type PB and Type PH panelboards, as well as compatible meter panels and multi-metering modules.

What wire gauge is accepted by the box lugs on this 100A breaker?

The terminal lugs accept conductors ranging from 4 AWG to 1/0 AWG. Ensure your wire sizing meets local electrical codes for a 100-amp circuit.

How does the CHB3100 connect to the panelboard bus?

It utilizes a bolt-on mounting connection. This provides a secure mechanical and electrical connection to the bus bars in PB and PH series panels, which is typical for industrial applications.

What type of protection does the LI trip function provide?

The fixed thermal-magnetic trip unit provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against short circuits.

Is the Eaton CHB3100 the same as the Cutler-Hammer CHB3100?

Yes. Eaton acquired the Cutler-Hammer brand, so this breaker serves as the direct, manufacturer-approved replacement for older Cutler-Hammer CHB3100 units.

Can this breaker be used in systems requiring a higher interrupting rating than 10kAIC?

No. The CHB3100 has a maximum interrupting capacity of 10kA at 240V AC. If your system fault current exceeds this, a breaker with a higher AIC rating is required to ensure safe operation.

    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.
