2CSR275075R2254

The ABB DSB201 M AC-C25/0.1 (part number 2CSR275075R2254) is a residual current circuit breaker with overcurrent protection (RCBO), designed to protect electrical circuits against overloads, short circuits and earth-leakage faults. It combines residual-current protection and overcurrent protection in a compact device suitable for installation in compatible distribution boards and electrical panels.

The device has a rated current of 25 A, a C-type tripping characteristic and a rated residual operating current of 100 mA. Its 1P+N configuration is intended for single-phase circuits, switching the phase and neutral as specified by the manufacturer. The AC-type residual-current detection is designed for sinusoidal alternating residual currents.

It is suitable for electrical distribution applications in residential, commercial and industrial installations where the specified ratings and protection characteristics meet the circuit design requirements. Installation should be carried out by a qualified electrician, following ABB's technical documentation and applicable electrical standards.
