Why Choose the ABB DS201MC20AC100 RCBO?
The ABB DS201MC20AC100, manufacturer type DS201 M C20 AC100, is a compact residual current circuit breaker with overcurrent protection (RCBO) for protecting single-phase final circuits against overloads, short circuits and earth leakage faults. Part of ABB's System pro M compact DS201 M range, it combines overcurrent and residual current protection in a two-module DIN-rail device.
This RCBO has a 20 A rated current, C tripping characteristic and 10 kA rated short-circuit breaking capacity. Its Type AC residual current function detects sinusoidal alternating residual currents, while the 100 mA rated residual operating current provides earth leakage protection for appropriate AC circuits.
The 1P+N configuration incorporates one protected pole together with neutral switching for single-phase installations. Rated for 230–240 V AC operation, the DS201 M C20 AC100 provides a space-efficient solution for distribution boards, switchboards and control panels requiring coordinated overcurrent and Type AC residual current protection.

Reliable Combined Protection for Single-Phase Circuits
The ABB DS201 M C20 AC100 combines the functions normally associated with a miniature circuit breaker and a residual current device. It protects wiring and connected equipment against overload and short-circuit currents while monitoring for sinusoidal alternating residual currents flowing to earth.
Its 20 A C-curve overcurrent characteristic, 100 mA Type AC residual current sensitivity and 10 kA Icn breaking capacity provide coordinated circuit protection in one compact device. This makes the DS201MC20AC100 suitable for appropriate single-phase installations where both thermal-magnetic overcurrent protection and Type AC earth leakage detection are required.
Typical Applications
- Single-phase final circuit protection.
- Commercial building electrical distribution.
- Industrial distribution boards and control panels.
- Lighting and general-purpose electrical circuits.
- Circuits supplying suitable loads with moderate starting currents.
- Installations requiring combined overload, short-circuit and 100 mA Type AC residual current protection.
