ABB DSB201M APR-C20/0.1 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 has a rated current of 20 A, a residual operating current of 100 mA, a C-type tripping characteristic, and an APR high-immunity design that helps reduce unwanted tripping caused by transient electrical disturbances. It is suitable for DIN-rail mounting in compatible low-voltage electrical distribution panels.
