Why Choose the ABB DS202CRMC20A30110V RCBO?
The ABB DS202CRMC20A30110V is a compact 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and residual earth fault currents. Part of the ABB DS202CR M series, this variant is configured for 110 V applications and combines residual current and overcurrent protection within a space-efficient modular device.
This RCBO uses Type A residual current detection, providing protection against sinusoidal alternating and pulsating DC residual currents. Its Type C tripping characteristic is suitable for circuits where moderate inrush currents may occur, while its 30 mA residual current sensitivity provides additional protection against electric shock in appropriate installations.
With a rated current of 20 A, rated residual operating current of 30 mA and 110 V configuration, the DS202CRMC20A30110V provides combined circuit protection in a compact DIN-rail format. ABB order code 2CSR772199R1204 identifies this specific DS202CR M C20 A30 110V configuration.
