The ABB DSB201 M AC-C20/0.03 is a residual current circuit breaker with integrated overcurrent protection (RCBO), designed to protect compatible single-phase electrical circuits against earth-leakage currents, overloads and short circuits. It combines residual-current protection and miniature circuit-breaker functionality in one compact device. The unit has a rated current of 20 A, a residual operating current of 30 mA, a C-curve tripping characteristic and Type AC residual-current detection. Its 1P+N configuration is intended for compatible single-phase installations, and it is designed for DIN-rail mounting.
