Why Choose the ABB DSE201 M B40 A10 RCBO?
The ABB DSE201 M B40 A10 is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and earth fault currents. As part of the ABB DSE201 M eRCBO series, it combines residual-current and overcurrent protection in a space-efficient device for commercial and industrial electrical installations.
This Type A RCBO provides protection against sinusoidal alternating and pulsating DC residual currents while incorporating a B tripping characteristic for overcurrent protection. The DSE201 M series combines multiple protective functions within one DIN-rail-mounted device, helping simplify electrical distribution-board design while providing individual protection for final circuits.
With a rated current of 40 A, rated residual operating current of 10 mA and rated short-circuit capacity of 10 kA, the DSE201 M B40 A10 provides sensitive earth-fault protection together with dependable overload and short-circuit protection. Its 1P+N configuration makes it suitable for a wide range of single-phase commercial and industrial circuits.
