ABB DSB201 M A-C20/0.03 is a single-phase residual current circuit breaker with integrated overcurrent protection, designed to protect electrical circuits against overloads, short circuits, and earth-leakage currents. It features a rated current of 20 A, a residual operating current of 30 mA, a C-type tripping characteristic, and Type A residual-current detection. The device is designed for DIN-rail mounting in low-voltage electrical distribution panels and provides protection against sinusoidal alternating and pulsating direct earth-fault currents.
