Why Choose the ABB DS201 M C25 A100 RCBO?
The ABB DS201 M C25 A100 is a high-performance 1P+N Type A residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth leakage faults. Part of the proven ABB DS200 / DSH200 RCBO product group, this DS201 M device combines residual current and overcurrent protection in a compact two-module unit for residential, commercial and industrial electrical installations.
This RCBO provides Type A residual current protection, enabling detection of sinusoidal AC residual currents and pulsating DC residual currents. Its C tripping characteristic makes it suitable for circuits where moderate inrush currents may occur, while the combined RCBO design simplifies distribution-board installations by providing multiple protective functions within a single device.
With a rated current of 25 A, rated residual operating current of 100 mA and rated short-circuit breaking capacity of 10 kA, the DS201 M C25 A100 provides robust circuit protection for demanding installations. The device uses a 1P+N configuration, with one protected pole and two-pole switching, and is designed for DIN-rail installation in electrical distribution equipment.

Reliable Combined Circuit and Residual Current Protection
RCBOs such as the ABB DS201 M combine the functions of a miniature circuit breaker and residual current device in a single unit. The device disconnects the protected circuit in response to excessive overcurrent, short-circuit conditions or qualifying residual earth leakage currents, helping protect electrical installations and connected equipment.
The Type A residual current characteristic enables the DS201 M C25 A100 to respond to sinusoidal alternating residual currents as well as pulsating DC residual currents. Combined with its C curve overcurrent characteristic and 10 kA breaking capacity, this makes the RCBO suitable for a broad range of modern residential, commercial and industrial single-phase circuits.
Typical Applications
- Residential electrical distribution boards.
- Commercial building electrical installations.
- Industrial single-phase final circuits.
- Lighting and general electrical circuits.
- Electrical equipment with moderate starting or inrush currents.
- Distribution circuits requiring combined overcurrent and earth leakage protection.
