2CSR275075R3324

The ABB DSB201 M AC-C32/0.3, product code 2CSR275075R3324, is a residual current circuit breaker with overcurrent protection (RCBO) designed to protect compatible low-voltage electrical circuits against overloads, short circuits and earth-leakage faults.

The device has a rated current of 32 A, a C-type tripping characteristic and a rated residual operating current of 300 mA (0.3 A). Its Type AC residual-current detection responds to sinusoidal alternating residual currents. The 1P+N configuration is intended for compatible single-phase electrical circuits. Its compact two-module design supports DIN-rail installation in electrical distribution boards and control panels.

This RCBO is suitable for residential, commercial and industrial distribution applications where the rated current, leakage sensitivity and breaking capacity meet the installation requirements. A 300 mA residual-current setting is generally used for installation or equipment protection and does not replace 30 mA additional protection against electric shock where required. Selection and installation should follow ABB's technical documentation and applicable electrical standards.
