The Siemens 5SU1624-2RC63 is a combined residual current circuit breaker with overcurrent protection (RCBO) from the SENTRON 5SU1 series, integrating a 63 A thermal-magnetic overcurrent trip with a 300 mA Type AC residual current device in a single 4-module (72 mm wide) DIN-rail housing. The Type AC RCD detects sinusoidal AC earth faults only, so it is suited for circuits without non-sinusoidal or pulsating DC fault currents (resistive heaters, lighting, general socket outlets in commercial or residential distribution boards).
