Why Choose the ABB DS201MB40AC30 RCBO?

The ABB DS201MB40AC30 is a high-performance 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. With ABB order code 2CSR275080R1405, this device forms part of the ABB DS200 / DS201 M RCBO range for residential, commercial and industrial electrical distribution applications.

Combining miniature circuit breaker and residual current protection within a single compact device, the DS201 M B40 AC30 provides comprehensive circuit protection while helping reduce the number of separate protective devices required in a distribution board. Its Type AC residual current detection responds to sinusoidal alternating residual currents, while the B tripping characteristic is suited to circuits with relatively low inrush currents.

With a rated current of 40 A, a 30 mA rated residual operating current and a 230 V AC rated voltage, the DS201MB40AC30 is designed for single-phase final circuits requiring combined overcurrent and earth leakage protection. Its 10 kA rated short-circuit breaking capacity, thermal-magnetic tripping mechanism and compact two-module format provide dependable protection in modern electrical installations.

Key Advantages

  • Combined RCBO protection against overload, short circuit and residual current faults.
  • 40 A rated current for higher-current single-phase final circuits.
  • 30 mA residual current sensitivity for additional protection against electric shock.
  • Type AC residual current detection for sinusoidal alternating earth leakage currents.
  • B tripping characteristic suitable for circuits with relatively low inrush currents.
  • 1P+N configuration with one protected pole and switched neutral.
  • 10 kA rated short-circuit breaking capacity for robust fault protection.
  • Compact two-module DIN rail format for efficient use of distribution board space.

Key Features

  • ABB DS201 M RCBO series.
  • 40 A rated current.
  • 30 mA rated residual operating current.
  • 230 V AC rated voltage.
  • 1P+N pole configuration.
  • Type AC residual current protection.
  • B-curve tripping characteristic.
  • 10 kA rated short-circuit breaking capacity (Icn).

Reliable Combined Circuit Protection

RCBOs such as the ABB DS201MB40AC30 combine overcurrent and residual current protection within one modular device. The thermal-magnetic mechanism responds to overload and short-circuit conditions, while the residual current function detects sinusoidal alternating leakage currents to earth and disconnects the circuit when the specified threshold is reached.

The DS201 M range is designed for end-user single-phase circuits in residential, commercial and industrial installations. Its compact 1P+N construction, 30 mA residual current sensitivity and 10 kA breaking capacity provide dependable circuit protection while helping make efficient use of space within modular distribution boards.

Typical Applications

  • Residential electrical distribution boards.
  • Commercial single-phase final circuits.
  • Industrial electrical distribution systems.
  • Higher-current single-phase power circuits where appropriate.
  • Lighting and general electrical circuits.
  • Control panels and auxiliary electrical circuits.
  • Building electrical distribution systems.
