2CSR275075R3164

The ABB DSB201M AC-C16/0.3, product code 2CSR275075R3164, 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.

The device has a rated current of 16 A, a C-type tripping characteristic and a rated residual operating current of 300 mA (0.3 A). Its Type AC residual-current detection is designed to respond to sinusoidal alternating residual currents. The 1P+N configuration is suitable for compatible single-phase circuits, while its compact two-module design supports DIN-rail installation in electrical distribution boards and control panels.

This RCBO is intended for residential, commercial and industrial electrical distribution applications where its current rating, leakage sensitivity and breaking capacity are appropriate for the circuit design. The 300 mA residual-current setting is generally used for installation or equipment protection rather than the additional personal protection commonly provided by 30 mA devices. Selection and installation should follow ABB's technical documentation and applicable electrical standards.
