Product FAQs
7 answersWhat load centers are compatible with the Eaton BR245?
The BR245 is UL listed for use in Eaton and Cutler-Hammer Type BR load centers. It is also a recognized, UL-approved replacement for legacy Bryant, Westinghouse, and Challenger panels that accept 1-inch plug-on breakers.
Can I install the Eaton BR245 in a Square D or Siemens panel?
No. Installing an Eaton BR breaker in a Square D or Siemens panel is not UL approved and violates National Electrical Code (NEC) listing requirements for panelboards.
Can I use the BR245 to replace an older Bryant or Westinghouse breaker?
Yes, the Eaton BR245 is the direct, UL-approved replacement for legacy Bryant and Westinghouse 45A 2-pole breakers utilizing the 1-inch plug-on format.
How many panel spaces does the BR245 require?
This 2-pole breaker requires two standard 1-inch spaces, occupying a total of 2 inches on the panel bus.
Is the Eaton BR245 rated for HVAC equipment?
Yes, Eaton Type BR 2-pole circuit breakers carry a listing for HACR (Heating, Air Conditioning, and Refrigeration) applications, making them suitable for HVAC branch circuits.
How do I reset the BR245 after a trip event?
When tripped, the breaker handle moves to a center position. To restore power, push the handle firmly to the OFF position to reset the internal mechanism, then push it back to the ON position.
Is the BR245 an AFCI or GFCI breaker?
No, the BR245 is a standard thermal-magnetic circuit breaker. It does not provide arc-fault (AFCI) or ground-fault (GFCI) protection.
