Why Choose the ABB DS201MC25A300 RCBO?
The ABB DS201MC25A300, manufacturer type DS201 M C25 A300, is a compact and highly reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the advanced ABB DS201 M / System pro M compact series, it combines residual current and overcurrent protection in a two-module DIN-rail device.
This Type A RCBO detects sinusoidal alternating and pulsating DC residual currents, while its C-curve overcurrent characteristic is suitable for circuits with moderate starting and inrush currents. The DS201 M range provides one protected pole with two-pole switching, helping simplify distribution board design while providing dedicated protection and isolation for individual circuits.
With a rated current of 25 A, a rated residual operating current of 300 mA and a rated short-circuit breaking capacity of 10 kA, the DS201 M C25 A300 is suitable for residential, commercial and industrial electrical installations. Its 230 V AC rating and compact 1P+N configuration make it a practical solution for single-phase distribution systems requiring combined overcurrent and residual current protection.

Reliable Combined Circuit Protection
RCBOs combine the functions of a miniature circuit breaker and residual current device in a single protective component. The ABB DS201 M series protects single-phase circuits against overload and short-circuit currents while also detecting residual earth fault currents, providing coordinated protection within compact electrical distribution systems.
The Type A characteristic enables detection of sinusoidal AC and pulsating residual currents, while the 300 mA residual current rating can be used for appropriate fault and fire-protection applications where this sensitivity is specified. Together with its C-curve characteristic and 10 kA Icn rating, the DS201 M C25 A300 is designed for dependable use across residential, commercial and industrial installations.
