Why Choose the ABB DS201MB20AC100 RCBO?

The ABB DS201MB20AC100, manufacturer type DS201 M B20 AC100, is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase 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 within one DIN-rail device.

This RCBO has a 20 A rated current, B 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 electrical circuits.

The 1P+N configuration incorporates one protected pole together with neutral switching for single-phase installations. With a rated operational voltage of 230–240 V AC, the DS201 M B20 AC100 provides a compact solution for distribution boards, switchboards and control panels requiring coordinated overcurrent and Type AC residual current protection.

Key Advantages

  • Combines overload, short-circuit and residual current protection in one RCBO.
  • 20 A rated current with B-curve tripping characteristic.
  • 100 mA Type AC residual current protection for sinusoidal alternating residual currents.
  • 10 kA rated short-circuit breaking capacity for dependable fault protection.
  • 1P+N configuration designed for single-phase circuits.
  • B-curve characteristic is suited to appropriate loads with relatively low starting and inrush currents.
  • Compact two-module DIN-rail construction simplifies integration into modular distribution equipment.

Reliable Combined Protection for Single-Phase Circuits

The ABB DS201 M B20 AC100 combines the protective functions of a miniature circuit breaker and a residual current device. It protects connected wiring and equipment against overload and short-circuit currents while monitoring the circuit for sinusoidal alternating residual currents flowing to earth.

Its 20 A B-curve overcurrent characteristic, 100 mA Type AC residual current sensitivity and 10 kA Icn breaking capacity provide coordinated protection in one compact device. This makes the DS201MB20AC100 suitable for appropriate single-phase installations requiring both thermal-magnetic overcurrent protection and Type AC earth leakage detection.

Typical Applications

  • Single-phase electrical distribution circuits.
  • Residential and commercial distribution boards.
  • Commercial building electrical installations.
  • Industrial distribution and control panels.
  • Lighting and general-purpose circuits with suitable load characteristics.
  • Circuits requiring combined overload, short-circuit and 100 mA Type AC residual current protection.
