2CSR275180R2105 ABB DS201MB10A100 RCBO 1P+N B10 Type A 100 mA

Why Choose the ABB DS201MB10A100 RCBO?

The ABB DS201MB10A100 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and residual earth fault currents. With ABB order code 2CSR275180R2105, it forms part of the established ABB DS200 / DS201 M RCBO range for residential, commercial and industrial electrical distribution applications.

Combining overcurrent and residual current protection within a single modular device, the DS201 M B10 A100 helps simplify distribution board design while providing coordinated circuit protection. Its Type A residual current detection responds to sinusoidal alternating and pulsating DC residual currents, while the B tripping characteristic is suited to circuits with relatively low inrush currents.

With a rated current of 10 A, a 100 mA rated residual operating current and a 230 V AC rated voltage, the DS201MB10A100 provides combined protection for suitable single-phase circuits. Its 10 kA rated short-circuit breaking capacity, compact 1P+N arrangement and DIN rail construction make it a robust solution for modular electrical distribution systems.

Reliable Combined Circuit Protection

RCBOs such as the ABB DS201MB10A100 combine residual current and overcurrent protection within one modular device. The overcurrent section responds to overload and short-circuit conditions, while the Type A residual current function detects both sinusoidal alternating and pulsating DC earth fault currents, providing broader residual current detection than a Type AC device.

The DS201 M range provides compact protection for single-phase electrical distribution circuits. The DS201MB10A100 combines a 10 A B-curve overcurrent characteristic with 100 mA Type A residual current sensitivity, making it suitable for appropriately designed residential, commercial and industrial circuits where these specific protection characteristics are required.

Typical Applications

• Residential single-phase electrical distribution circuits.
• Commercial electrical distribution systems.
• Industrial single-phase circuits.
• Lighting and general circuits where a B-curve characteristic is appropriate.
• Control panels and auxiliary electrical circuits.
• Circuits supplying suitable electronic equipment capable of producing pulsating DC residual currents.
• Applications requiring combined overcurrent and 100 mA Type A residual current protection.
