Why Choose the ABB DS204MAC400.03 RCBO?
The ABB DS204MAC400.03, manufacturer type DS204 M A-C40/0.03, is a four-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults. As part of the ABB DS200 M series, it combines overcurrent and residual current protection within a single DIN-rail device for dependable electrical distribution.
This RCBO has a 40 A rated current, C tripping characteristic and 10 kA rated short-circuit breaking capacity according to IEC/EN 61009-1. Its Type A residual current protection detects sinusoidal AC residual currents as well as pulsating DC residual currents, making it suitable for modern electrical circuits incorporating electronic equipment.
With a rated residual operating current of 30 mA and a 400 V AC rated voltage, the DS204 M A-C40/0.03 provides additional protection against electric shock while protecting wiring and connected equipment against overcurrent conditions. Its four-pole configuration and modular DIN-rail construction make it well suited to commercial and industrial three-phase distribution systems.
