2CSR275075R3104

The ABB DSB201 M AC-C10/0.3, product code 2CSR275075R3104, is a residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth-leakage faults in compatible low-voltage electrical installations.

This device has a rated current of 10 A, a C-type tripping characteristic and a rated residual operating current of 300 mA (0.3 A). It uses Type AC residual-current detection, designed to respond to sinusoidal alternating residual currents. Its 1P+N configuration is intended for compatible single-phase circuits, while its compact design supports DIN-rail mounting in electrical distribution boards and control panels.

The device is suitable for electrical distribution applications where a 10 A circuit rating and 300 mA residual-current protection are appropriate to the installation design. Selection should take account of the connected load, fault-current conditions and applicable electrical standards. Installation should be carried out by a qualified electrician in accordance with ABB's technical documentation.
