Product FAQs
4 answersWhat type of panel is required for the BRH380 breaker?
The BRH380 is designed exclusively for use in Eaton or legacy Cutler-Hammer Type BR load centers. As a 3-pole breaker, it requires a 3-phase panel to operate correctly.
What is the difference between the Eaton BR380 and the BRH380?
The primary difference is the short-circuit interrupting rating. The standard BR380 is rated at 10kAIC, while the BRH380 is a high-interrupting version rated at 22kAIC.
Is the Eaton BRH380 circuit breaker HACR rated?
Yes, all Eaton Type BR three-pole circuit breakers, including the BRH380, are HACR rated for use with compatible heating, air conditioning, and refrigeration equipment.
Can I use the Eaton BRH380 to replace an older Cutler-Hammer BRH380?
Yes. Eaton acquired Cutler-Hammer, and the current Eaton BRH380 is the direct replacement for legacy Cutler-Hammer breakers with the exact same catalog number.
