ABB 2CSF202003R3400 FH202 AC-40/0.3 2P 40A 300mA DIN-Rail Residual Current Circuit Breaker RCCB

The ABB FH202 AC-40/0.3 (SKU: 2CSF202003R3400) is a 2-pole 40 A residual current circuit breaker (RCCB) from the ABB FH200 series, designed to provide reliable earth-fault protection in residential and light commercial installations. Rated at 300 mA sensitivity and mounting directly onto standard DIN-rail, this RCCB detects leakage currents and disconnects the circuit to protect personnel and equipment from electric shock hazards. Compact at 35 mm × 85 mm × 69 mm and weighing just 200 g, the FH202 AC-40/0.3 is an ideal choice for space-constrained distribution boards.
