Product FAQs
6 answersWhat is the difference between the Eaton BR245 and the BRH245?
Both are 45-amp, 2-pole breakers for Eaton BR load centers, but they have different short-circuit interrupting ratings. The standard BR245 is rated at 10 kAIC, while the BRH245 is a high-interrupting breaker rated at 22 kAIC.
Can I use the BRH245 in an older Bryant or Westinghouse load center?
Yes. Eaton BR series breakers, including the BRH245, are UL-listed to replace older Bryant, Westinghouse Type BR, and Challenger breakers in compatible load centers. Always verify your specific panel labeling to ensure UL compliance.
Will this breaker fit in an Eaton CH series panel?
No. Eaton BR and CH series breakers are not interchangeable. The BRH245 is a 1-inch per pole plug-on breaker designed exclusively for Type BR load centers, whereas CH panels require 3/4-inch CH series breakers.
What does the H in the BRH245 catalog number indicate?
The H designates this as a high-interrupting capacity breaker. It provides a 22 kAIC rating at 240V, which is required in systems with higher available fault currents compared to standard 10 kAIC residential breakers.
Are the terminals on the BRH245 rated for aluminum wire?
Yes, the box lug terminals are dual-rated for both copper and aluminum conductors. They accept wire sizes from 14 AWG to 4 AWG.
Is the Eaton BRH245 HACR rated for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific circuit protection.
