The ABB DSB201M A-C40/300mA is a 1P+N (2-pole width) Residual Current Circuit Breaker with Overcurrent Protection (RCBO) engineered for residential, commercial, and industrial installations. It integrates overcurrent protection (against overloads and short-circuits) and earth leakage protection (pulsating direct and sinusoidal alternating earth fault currents – Type A) into a single compact 2-module unit. It features a 10 kA breaking capacity, type A waveform sensitivity, and a C-curve tripping characteristic.
