Product FAQs
6 answersWhich specific Challenger breaker part numbers does this replace?
The Eaton BR120 is the UL approved, direct replacement for legacy Challenger Type C circuit breakers, including the C120 and C120-R part numbers.
Why is this breaker listed for use with older Westinghouse and Bryant panels?
Eaton acquired the Westinghouse and Bryant electrical distribution lines. The Eaton BR series uses the exact same bus bar connection design, making them the official, backward-compatible replacement for those legacy panels.
Does this breaker meet the requirements for HVAC equipment?
Yes, it is HACR rated. This certifies the breaker for use with heating, air conditioning, and refrigeration equipment that requires a dedicated HACR protective device.
Is the BR120 suitable for switching fluorescent lighting loads?
Yes, this breaker carries an SWD (Switching Duty) rating, meaning it is certified for daily use as a switch to control 120-volt fluorescent lighting circuits.
How much physical space does this breaker require on the bus bar?
It is a standard 1-inch format breaker, meaning it will occupy a single 1-inch space in your load center.
Does this standard BR breaker provide GFCI or AFCI protection?
No, this is a standard thermal-magnetic breaker that provides only overload and short-circuit protection. It does not include Ground Fault (GFCI) or Arc Fault (AFCI) safety features.
