Why Choose the ABB DS203MAC320.03 RCBO?
The ABB DS203MAC320.03, manufacturer type code DS203 M A-C32/0.03, is a high-performance 3-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 overcurrent and residual current protection in a single modular device for commercial and industrial electrical distribution systems.
This Type A RCBO detects sinusoidal AC residual currents as well as pulsating DC residual currents, making it suitable for circuits supplying many types of modern electrical and electronic equipment. Its Type C tripping characteristic accommodates moderate inrush currents, 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 32 A, a 3-pole configuration and a 10 kA rated short-circuit capacity, the DS203 M A-C32/0.03 provides coordinated protection for three-phase electrical circuits. Its compact DIN-rail format supports straightforward integration into commercial distribution boards, industrial control panels and modular electrical installations.
