2CSR275080R1404 ABB DS201MC40AC30 RCBO 1P+N C40 Type AC 30 mA

Why Choose the ABB DS201MC40AC30 RCBO?

The ABB DS201MC40AC30 is a high-performance 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. With ABB order code 2CSR275080R1404, this device forms part of the established ABB DS200 / DS201 M RCBO range for residential, commercial and industrial electrical distribution applications.

Combining miniature circuit breaker and residual current protection within a single two-module device, the DS201 M C40 AC30 provides comprehensive circuit protection while helping reduce the space required inside distribution boards. Its Type AC residual current detection responds to sinusoidal alternating residual currents, while the C tripping characteristic is suitable for circuits and equipment with moderate inrush currents.

With a rated current of 40 A, a 30 mA rated residual operating current and a 230–240 V AC rated operational voltage, the DS201MC40AC30 is suitable for single-phase final circuits requiring combined overcurrent and earth leakage protection. Its 10 kA rated short-circuit breaking capacity provides robust fault protection for demanding electrical installations.

Reliable Combined Circuit Protection

RCBOs such as the ABB DS201MC40AC30 combine overcurrent and residual current protection within one modular device. The thermal-magnetic protection responds to overload and short-circuit conditions, while the residual current function detects sinusoidal alternating leakage currents to earth and disconnects the circuit when the specified threshold is reached.

The DS201 M range is designed for end-user single-phase circuits in residential, commercial and industrial installations. Its compact 1P+N construction, 30 mA residual current sensitivity and high short-circuit breaking capacity provide dependable circuit protection while helping make efficient use of space within modular distribution boards.
