Why Choose the ABB DS201MC40AC300 RCBO?

The ABB DS201MC40AC300, manufacturer type DS201 M C40 AC300, is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults. As part of the ABB DS200 / DS201 M series, it integrates residual current and overcurrent protection within a single DIN-rail device for single-phase electrical circuits.

This RCBO has a rated current of 40 A, a Type C tripping characteristic and a rated residual operating current of 300 mA. Its Type AC residual current characteristic is designed to detect sinusoidal alternating residual currents, providing earth leakage protection for suitable conventional AC electrical loads.

With a rated voltage of 230 V AC and a rated short-circuit capacity of 10 kA, the DS201 M C40 AC300 provides robust protection for suitable single-phase low-voltage distribution applications. Its 1P+N configuration combines overcurrent and residual current protection in one device, helping simplify distribution board design and installation.

Key Advantages

  • Combined residual current and overcurrent protection in one RCBO.
  • 40 A rated current for suitable single-phase circuits.
  • 300 mA residual current sensitivity for earth leakage protection.
  • Type AC residual current detection for sinusoidal alternating residual currents.
  • Type C tripping characteristic suitable for circuits with moderate inrush currents.
  • 10 kA rated short-circuit capacity for robust fault protection.
  • Compact 1P+N configuration for single-phase distribution systems.
  • DIN-rail mounting for straightforward integration into electrical distribution boards.

Key Features

  • ABB DS201 M RCBO series.
  • 1P+N configuration for single-phase circuits.
  • 40 A rated current.
  • 300 mA rated residual operating current.
  • Type AC residual current characteristic.
  • C-curve overcurrent characteristic.
  • 230 V AC rated voltage.
  • 50/60 Hz rated frequency.
  • 10 kA rated short-circuit capacity.
  • DIN-rail format for installation in electrical distribution assemblies.

Reliable Combined Circuit Protection

An RCBO combines residual current protection with overload and short-circuit protection in a single device. The ABB DS201 M C40 AC300 monitors the protected circuit for sinusoidal alternating earth leakage currents while also disconnecting the circuit when excessive current occurs because of an overload or short circuit.

The 300 mA residual current sensitivity provides earth leakage protection for applications where this operating threshold is specified, while the C-curve overcurrent characteristic accommodates moderate starting and inrush currents. This combination makes the DS201 M C40 AC300 suitable for appropriately designed single-phase circuits requiring coordinated residual current and overcurrent protection.

Typical Applications

  • Commercial electrical distribution boards.
  • Industrial single-phase distribution and auxiliary circuits.
  • Building services and fixed electrical equipment circuits.
  • Circuits supplying loads with moderate starting currents.
  • Circuits specified for 300 mA residual current protection.
  • Installations requiring combined overload, short-circuit and earth leakage protection.
