Enphase BRK-40A-2P-240V-B 40A 240VAC Dual Pole Eaton BR Circuit Breaker with Hold Down Support

Enphase 40A 2-Pole 240V Eaton BR Circuit Breaker with Hold Down Support (BRK-40A-2P-240V-B)

The Enphase 40A 2-Pole 240V Eaton BR Circuit Breaker (BRK-40A-2P-240V-B) is a dual-pole thermal-magnetic circuit breaker engineered for branch circuit overcurrent protection in Enphase solar PV and energy storage applications. Compatible with the Enphase IQ System Controller and IQ System Controller 2, this 40-amp breaker provides protective switching across split-phase 240V AC circuits.

Featuring a short-circuit interrupt capacity of approximately 10 kAIC, this Eaton BR240B / BR series compatible breaker includes hold-down support capability. Per National Electrical Code (NEC) regulations, plug-in breakers connected to grid-forming energy sources (such as IQ8 Series Microinverters, IQ Batteries, or backup generators) require a hold-down kit (sold separately).
