2CSR275189R1405 ABB DS201 M B40 A30 110V RCBO 1P+N 40 A 30 mA Type A

Why Choose the ABB DS201 M B40 A30 110V RCBO?

The ABB DS201 M B40 A30 110V is a compact and dependable 1P+N Type A residual current circuit breaker with overcurrent protection (RCBO) designed to protect 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 residual current and overcurrent protection within a single DIN-rail 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 B tripping characteristic is suited to circuits with relatively low starting and inrush currents, while the 30 mA residual current sensitivity provides protection against indirect contact and additional protection against direct contact.

With a rated current of 40 A, a rated residual operating current of 30 mA and a rated short-circuit breaking capacity of 10 kA, the DS201 M B40 A30 110V provides robust combined protection for compatible single-phase circuits. This DS201 M 110V variant has a minimum test-button operating voltage of 110 V AC and is suitable for 230 V AC applications.

Reliable Combined Circuit and Residual Current Protection

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 B40 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 B40 A30 110V to respond to sinusoidal alternating residual currents as well as pulsating DC residual currents. Combined with its B curve overcurrent characteristic, 30 mA residual current sensitivity and 10 kA rated 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 relatively low starting and inrush currents.
• Applications requiring a minimum test-button operating voltage of 110 V AC.
• Single-phase circuits requiring combined overcurrent and residual current protection.
