2CSR275189R1404 ABB DS201 M C40 A30 110V RCBO 1P+N 40 A 30 mA Type A

Why Choose the ABB DS201 M C40 A30 110V RCBO?

The ABB DS201 M C40 A30 110V is a high-performance 1P+N Type A residual current circuit breaker with overcurrent protection (RCBO) designed to protect end-user single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the established ABB DS200 / DSH200 RCBO product group, it combines overcurrent and residual current protection within a compact two-module device for residential, commercial and industrial electrical installations.

This RCBO provides Type A residual current protection, enabling detection of sinusoidal AC residual currents and pulsating DC residual currents. Its C tripping characteristic is suitable for circuits with moderate starting and inrush currents, while the 30 mA residual current sensitivity provides additional protection against direct contact as well as protection against indirect contact.

With a rated current of 40 A, rated residual operating current of 30 mA and 10 kA short-circuit breaking capacity, the DS201 M C40 A30 110V provides robust protection for demanding single-phase applications. This special DS201 M 110V variant has a minimum test-button operating voltage of 110 V AC and is suitable for applications up to 230 V AC.

Reliable Motor Control for Industrial Machinery

RCBOs such as the ABB DS201 M combine the functions of a miniature circuit breaker and residual current device within a single protective unit. The DS201 M C40 A30 110V can disconnect the protected circuit in response to overload, short-circuit or qualifying residual earth fault currents, providing coordinated protection while reducing the need for separate protective devices.

The Type A residual current characteristic enables the DS201 M C40 A30 110V to respond to sinusoidal alternating residual currents as well as pulsating DC residual currents. Combined with its C curve overcurrent characteristic, 30 mA sensitivity and 10 kA breaking capacity, it provides comprehensive protection for compatible residential, commercial and industrial single-phase circuits.

Typical Applications

• Residential electrical distribution systems.
• Commercial building electrical installations.
• Industrial single-phase circuits.
• Control panels and auxiliary electrical systems.
• Circuits with moderate starting or inrush currents.
• Applications requiring a minimum test-button operating voltage of 110 V AC.
• Single-phase circuits requiring combined overcurrent and residual current protection.
