The ABB DSB201 M AC-C25/0.03 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. With a rated current of 25 A, a rated residual operating current of 30 mA, a C-curve tripping characteristic and Type AC residual-current detection, it helps protect against sinusoidal alternating earth-fault currents and overcurrent conditions. Its 1P+N configuration is designed for compatible single-phase installations and DIN-rail mounting.
