Product FAQs
8 answersWhat panels are compatible with the BRH330 circuit breaker?
The BRH330 is designed for 3-phase Eaton Type BR load centers. It is also UL-listed for use in compatible legacy Cutler-Hammer, Bryant, and Westinghouse panels that accept Type BR breakers.
Can I install the BRH330 in a single-phase load center?
No. The BRH330 is a 3-pole breaker and requires a 3-phase panel to properly connect to all three bus bars. It cannot be used in a standard single-phase panel.
How many panel spaces does the BRH330 require?
This 3-pole breaker requires three standard 1-inch spaces in a compatible 3-phase load center.
What is the difference between a standard BR330 and the BRH330?
The H in the BRH330 part number indicates a high interrupting rating. While a standard BR330 has a 10kAIC rating, the BRH330 is rated for 22kAIC at 240VAC, providing enhanced protection for systems with higher available fault currents.
Is the BRH330 suitable for HVAC equipment?
Yes, the BRH330 is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific circuit protection designation.
Does the BRH330 replace older Cutler-Hammer breakers?
Yes. Eaton acquired Cutler-Hammer, and the current Eaton BRH330 is the direct replacement for legacy Cutler-Hammer BRH330 breakers. It also replaces equivalent Bryant and Westinghouse models.
What type of wire can be used with the BRH330 terminals?
The box lug terminals on the BRH330 are dual-rated for both copper and aluminum conductors, accommodating wire sizes between 14 AWG and 4 AWG.
Does the BRH330 feature a common trip mechanism?
Yes, as a multipole breaker, the BRH330 features an internal common trip connection. If a fault occurs on any single pole, the mechanism will simultaneously open all three poles to safely disconnect the 3-phase circuit.
