High Immunity Type A 4 Pole RCBO – ADR440C A Type EV RCBO Kit Arc fault detection – bothThe ADR440C High Immunity Type A 4 Pole RCBO is a 40A protective device designed for three phase circuits where both AC and smooth DC leakage currents may occur. With 30mA residual current protection, 6mA DC detection, and a 10kA short circuit rating, it delivers reliable protection for higher load circuits such as EV chargers, heat pump systems, and commercial distribution boards. Installer Tip: Choose the 40A ADR440C for heavier three phase circuits
