Product FAQs
7 answersWhat type of electrical panels accept the BRH350?
The BRH350 is designed for use in 3-phase Eaton and Cutler-Hammer Type BR load centers. It requires three available 1-inch spaces on the busbar.
Can I use the BRH350 in place of a standard BR350?
Yes, the BRH350 shares the exact physical dimensions and plug-on mounting style as the standard BR350. It can be used as a direct replacement, offering a higher interrupting capacity for systems requiring up to 22kAIC.
What does the H in the BRH350 part number signify?
The H indicates a high-interrupting capacity. While standard BR series breakers are rated for 10kAIC, the BRH series is rated to safely interrupt up to 22,000 amps at 240VAC.
How much panel space does the BRH350 require?
As a 3-pole miniature circuit breaker in the BR family, it requires three standard 1-inch spaces in a compatible Type BR load center.
What are the recommended torque specifications for the terminal lugs?
For Eaton BR series 50A breakers, the standard torque specifications are 20 in-lbs for 14 to 10 AWG wire, 25 in-lbs for 8 AWG wire, and 27 in-lbs for 6 to 4 AWG wire. Always verify with the label on the specific breaker before installation.
Is the Eaton BRH350 the same as the Cutler-Hammer BRH350?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture these Type BR breakers under the Eaton brand. The BRH350 part number and physical design remain identical.
Does this breaker include arc fault or ground fault protection?
No, the BRH350 is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection. It does not include AFCI or GFCI functionality.
