Eaton / Cutler-Hammer BR2150 Miniature Circuit Breaker

This breaker is UL listed for Eaton, Cutler-Hammer, and legacy Bryant Type BR load centers. It requires two standard 1-inch spaces on the bus bar.

No. The BR2150 is strictly UL listed for use in Eaton, Cutler-Hammer, and legacy Bryant Type BR load centers. Installing it in panels from other manufacturers violates the UL listing and compromises safety.

Both are 150A, 2-pole breakers for Type BR panels, but they have different footprints. The BR2150 requires two 1-inch spaces, while the BJ2150 requires four 1-inch spaces. The BJ2150 is often used in newer installations or where a wider footprint is preferred for heat dissipation.

Yes, but application matters. The lugs accept 4 AWG to 2/0 AWG wire. Under NEC rules for residential single-phase dwelling services, 2/0 AWG aluminum is permitted for a 150A load due to the 83 percent ampacity rule. For standard branch circuits, you must use copper conductors (like 1/0 AWG or 2/0 AWG) to safely achieve a full 150A rating.

Yes, it can function as a main breaker in compatible 150A Type BR service entrance panels. It is also commonly used as a high-capacity branch breaker to feed subpanels or large equipment.

Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 150A disconnect.

Yes. As a 2-pole breaker, it utilizes an internal common trip mechanism. If an overload or short circuit occurs on either pole, both poles will trip simultaneously to safely disconnect the entire circuit.

No. This is a standard thermal-magnetic breaker that provides overload and short-circuit protection. It does not feature arc fault or ground fault detection.
