Why Choose the ABB DS203 AC-C10/0.03 RCBO?
The ABB DS203 AC-C10/0.03 is a reliable 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 RCBO series, it combines residual current and overcurrent protection in a single DIN rail-mounted device for commercial and industrial electrical installations.
This AC Type RCBO detects sinusoidal alternating residual currents, while its C tripping characteristic is suitable for general-purpose circuits and equipment with moderate starting currents. The integrated RCBO design simplifies distribution-board installation by combining the functions of a residual current device and miniature circuit breaker in one protective device.
With a rated current of 10 A, rated residual operating current of 30 mA and rated short-circuit breaking capacity of 6 kA, the DS203 AC-C10/0.03 provides dependable protection for three-phase circuits. Its three-pole configuration makes it particularly suitable for commercial and industrial distribution systems, machinery and control-panel applications.
