Product FAQs
5 answersWhat type of panel is required for the BRH320?
The BRH320 is designed exclusively for 3-phase Eaton Type BR load centers. As a 3-pole breaker, it requires three adjacent spaces on a 3-phase bus and cannot be used in standard single-phase residential panels.
What is the difference between Eaton BR and BRH breakers?
The difference is the short-circuit interrupting rating. Standard BR breakers are typically rated at 10 kAIC, while the BRH series features a high interrupting capacity of 22 kAIC at 240VAC for environments with higher available fault currents.
Is the BRH320 suitable for HVAC equipment?
Yes, the BRH320 is HACR rated. This means it has been tested and approved for use with heating, air conditioning, and refrigeration equipment that requires a breaker with this safety designation.
Is the Eaton BRH320 the same as the Cutler-Hammer BRH320?
Yes. Eaton acquired Cutler-Hammer and maintained the BR product line. The Eaton BRH320 is the exact, manufacturer-approved equivalent and direct replacement for older Cutler-Hammer BRH320 breakers.
Will the BRH320 fit in an Eaton CH series load center?
No. Eaton BR and CH series breakers have different physical dimensions and bus connections. The BRH320 is a 1-inch wide breaker that only fits Type BR panels, while CH panels require 3/4-inch wide Type CH breakers.
