Why Choose the ABB DS202MAB400.03 RCBO?
The ABB DS202MAB400.03, manufacturer type code DS202 M A-B40/0.03, is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. As part of the ABB DS200 M RCBO series, it combines miniature circuit breaker and residual current protection functions in a single factory-assembled device for commercial and industrial electrical installations.
This Type A RCBO detects sinusoidal AC residual currents as well as pulsating DC residual currents, providing enhanced protection for circuits containing modern electronic equipment. Its Type B tripping characteristic provides dependable overcurrent protection, while the 30 mA residual current sensitivity provides additional protection against electric shock and helps protect against earth leakage faults.
With a rated current of 40 A, 2-pole configuration and 10 kA rated short-circuit capacity, the DS202 M A-B40/0.03 is suited to demanding commercial and industrial distribution applications. ABB's factory-combined DS200 construction simplifies installation and wiring while providing coordinated residual-current and overcurrent protection in one DIN-rail-mounted device.
