Product FAQs
5 answersWhat panels are compatible with the Eaton BRX2125 circuit breaker?
The BRX2125 is designed for use in Eaton Type BR loadcenters and group metering applications, including 1MP, 1MM, and 3MM modular metering stacks. It is also backward compatible with legacy Cutler-Hammer, Bryant, and Westinghouse panels that accept Type BR breakers.
Where are BRX series breakers typically applied?
BRX breakers are designed for multi-tenant and commercial applications that require high fault current protection. Their standalone rating simplifies system design by allowing a two-tier series rating instead of requiring coordinated upstream devices.
What is the physical footprint of the BRX2125 in a panel?
It requires two standard 1-inch spaces, taking up a total of 2 inches of width on the busbar.
Can I use the Eaton BRX2125 to replace older Cutler-Hammer breakers?
Yes, Eaton manufactures the BRX2125 as a direct, UL-listed replacement for legacy Cutler-Hammer, Bryant, and Westinghouse BRX2125 circuit breakers.
Does the BRX2125 provide arc fault or ground fault protection?
No, this is a standard thermal-magnetic circuit breaker designed for overcurrent and short-circuit protection. It does not include AFCI or GFCI functionality.
