Why Choose the ABB S204M-C3UC Miniature Circuit Breaker?
The ABB S204M-C3UC is a robust four-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in AC and DC electrical installations. As part of the established ABB System pro M compact S200M UC series, it combines flexible AC/DC operation with a high breaking capacity and compact DIN-rail installation.
The S200M UC range is specifically designed for applications requiring protection on both alternating and direct current systems. Its universal-current design uses permanent magnets in the internal arcing chutes to assist with DC arc extinction, while the C tripping characteristic provides protection suitable for circuits with moderate inrush currents.
With a 3 A rated current, C tripping characteristic, four-pole configuration and 10 kA rated breaking capacity, the S204M-C3UC is suitable for industrial control panels, distribution systems, machinery and other electrical installations where dependable AC/DC circuit protection is required.
