Product FAQs
5 answersCan the Eaton BR150 replace older Challenger or Bryant breakers?
Yes. The Eaton BR150 is the manufacturer-approved, UL-listed replacement for 50A 1-pole breakers in Challenger, Bryant, and Westinghouse load centers. It directly replaces legacy part numbers such as the Challenger C150 and Bryant BR150.
Is this breaker suitable for HVAC equipment?
Yes, the Eaton BR150 is HACR rated. This makes it fully compliant for protecting heating, air conditioning, and refrigeration circuits that require a 50A, 1-pole HACR-designated breaker.
What wire gauge is typically required for this 50-amp breaker?
While the box lugs on the BR150 accept 14 AWG to 4 AWG copper or aluminum wire, a 50-amp circuit generally requires 6 AWG copper or 4 AWG aluminum conductors. Always verify with local electrical codes and the specific temperature rating of your wire insulation.
Can I install the BR150 in a Square D Homeline panel?
No. Although it has a 1-inch plug-on format, the BR150 is exclusively designed for Eaton Type BR, Bryant, Challenger, and Westinghouse load centers. It is not UL-listed or physically compatible with Square D Homeline or QO panels.
Does this breaker include ground fault or arc fault protection?
No. The BR150 is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection. It does not include GFCI or AFCI functionality.
