2CSR275075R2404

The ABB DSB201 M AC-C40/0.1, product code 2CSR275075R2404, is a residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth-leakage faults in electrical installations.

This device features a rated current of 40 A, a C-type tripping characteristic and a rated residual operating current of 100 mA. Its Type AC residual-current detection is designed to respond to sinusoidal alternating residual currents. The 1P+N configuration is intended for compatible single-phase electrical circuits, and its compact design supports DIN-rail installation in suitable distribution boards and electrical panels.

The device is suitable for residential, commercial and industrial electrical distribution applications where its current rating, leakage sensitivity and breaking capacity match the circuit design requirements. Installation should be performed by a qualified electrician in accordance with ABB's technical documentation and applicable electrical standards.
