Product FAQs
5 answersWhat is the modern replacement for the CA2100 circuit breaker?
The CA2100 is a legacy C-Frame breaker. If you need a modern equivalent for panel upgrades or replacements, the Eaton EHD2100 series serves as the official direct replacement.
Can the CA2100 replace older CC-frame breakers?
Yes, the CA2100 can be used as a direct substitute for legacy CC2100 circuit breaker models in existing electrical systems.
Which panelboards are compatible with the CA2100?
This unit-mount breaker is designed to install into classic Westinghouse CDP, FDP, and Pow-R-Line panelboards.
Are the trip settings on the CA2100 adjustable?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and instantaneous (LI) protection functions, meaning the trip curve cannot be adjusted in the field.
How is the CA2100 breaker installed?
The CA2100 is a unit-mount breaker with a feed-thru connection type, designed to be bolted directly into the chassis of compatible commercial and industrial panelboards.
