Product FAQs
6 answersWhat load centers are compatible with the BRH2110 breaker?
The BRH2110 is designed for use in Eaton Type BR load centers. It is also UL approved for use in legacy Cutler-Hammer, Bryant, Westinghouse, and Challenger load centers that accept Type BR breakers.
What does the H in the BRH2110 catalog number indicate?
The H indicates a high interrupting rating. While standard BR breakers are rated at 10 kAIC, the BRH series is rated at 22 kAIC, providing higher short-circuit protection for systems with higher available fault current.
What is the recommended torque for the box lug terminals on the BRH2110?
For Eaton BR breakers, the recommended terminal torque depends on the wire size. For 3 AWG to 1/0 AWG wire, torque the lugs to 45 in-lbs. For 4 AWG wire, torque to 27 in-lbs. Always verify the exact torque specifications printed on the side of the breaker.
Can the BRH2110 be used as a back-fed main breaker?
Yes, this breaker can be used as a back-fed main in compatible load centers. When installed as a back-fed main, the National Electrical Code requires it to be secured with an approved Eaton BR hold-down kit to prevent accidental removal from the bus bar.
Is the BRH2110 a direct replacement for older Bryant or Westinghouse breakers?
Yes. Eaton acquired the Bryant and Westinghouse electrical distribution lines. The Eaton BRH2110 is the direct, UL-listed replacement for obsolete Bryant, Westinghouse, and Challenger breakers with matching specifications.
What wire types are accepted by the BRH2110 terminals?
The box lugs on this breaker accept 4 AWG to 1/0 AWG copper or aluminum conductors. For proper installation, use wire rated for 60 or 75 degrees Celsius.
