Enphase BRK-40A-2P-240V 40A 2P Circuit Breaker

Enphase 40A 2-Pole 240V Circuit Breaker (BRK-40A-2P-240V)

The Enphase 40A 2-Pole 240V Circuit Breaker (BRK-40A-2P-240V) is a plug-in thermal-magnetic circuit breaker engineered for branch circuit overcurrent protection in residential solar PV and energy storage applications. Specifically designed for integration within Enphase equipment such as IQ Combiner boxes and Enpower / System Controller panels, this 2-pole breaker controls and disconnects both hot phases of a 120/240V split-phase AC circuit simultaneously.

Rated for a maximum continuous current of 40 Amps with an interrupt rating of approximately 10 kAIC, the BRK-40A-2P-240V provides reliable protection against overloads and short circuits. It is designed specifically for branch circuit protection in standard BR-type plug-in panel interiors, ensuring full compliance with electrical safety codes for solar backfeed applications.

• “2P (2-pole)” means it simultaneously disconnects both phases of a 240V circuit.
• “40A” is the maximum continuous current rating.
• Designed for branch circuit protection, not as a main breaker.
