Product FAQs
7 answersWhich panelboards are compatible with the CHB2110 circuit breaker?
This bolt-on breaker is designed specifically for use in older Cutler-Hammer Type PB and Type PH panelboards, as well as compatible meter panels.
Can I use a BAB series breaker instead of the CHB2110 in my PB panelboard?
No. While both are bolt-on breakers, they are designed for different panelboard types. You must use a CHB series breaker for Type PB and PH panelboards to ensure proper fit and UL compliance.
Is the Cutler-Hammer CHB2110 an obsolete circuit breaker?
No. Eaton continues to manufacture CHB series breakers as direct replacement parts for legacy Cutler-Hammer Type PB and PH distribution panels.
What type of wire material is approved for the box lugs on this breaker?
The box lug terminals on the CHB2110 are rated to accept both copper and aluminum conductors within the 4 to 1/0 AWG size range.
What does the LI trip function code mean on this breaker?
The LI code indicates that the breaker provides Long-Time and Instantaneous trip functions. This is a standard thermal-magnetic mechanism where the long-time function protects against overloads and the instantaneous function protects against short circuits.
How does the CHB2110 connect to the panelboard bus?
This is a bolt-on circuit breaker. It requires a mechanical bolted connection to the panelboard bus bars, which provides a secure electrical connection for commercial and industrial applications.
Will this breaker fit in a standard Eaton BR or CH residential load center?
No. The CHB2110 is a bolt-on breaker intended for commercial distribution panelboards like the Type PB. It will not fit in plug-on residential load centers such as the BR or CH series.
