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

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

The BRK-40A-2P-240V is a 2-pole, 40-amp circuit breaker commonly used in solar and residential electrical systems, especially with Enphase Energy equipment (e.g., Enpower / IQ combiner systems).

• “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.

• Rated Current: 40 Amps
• Voltage Rating: 120/240 VAC (split-phase)
• Poles: 2-pole (controls two hot lines simultaneously)
• Interrupt Rating: ~10 kAIC
• Type: Thermal-magnetic circuit breaker (standard protection type)
• Mounting: Plug-in style (commonly BR-type panels)
• Certification: UL listed
• Weight: ~0.9 lb (≈0.4 kg)
