ABB S203P-C4 3-pole 4 A C curve miniature circuit breaker with 25 kA breaking capacity for industrial, commercial and OEM circuit protection.
The ABB S203P-C4 is a high-performance 3-pole miniature circuit breaker (MCB) designed to provide dependable overload and short circuit protection for low voltage electrical installations. As part of the proven ABB System pro M Compact S200P range, it is engineered for industrial, commercial and OEM applications where high breaking capacity and reliable protection are essential.
Featuring a C tripping characteristic, the S203P-C4 is ideal for general power distribution circuits and equipment with moderate inrush currents, including lighting, socket circuits, control equipment and small motors. Its current limiting design helps reduce thermal and mechanical stress on connected equipment during fault conditions.
With a rated current of 4 A, a 3-pole configuration and a 25 kA breaking capacity, the S203P-C4 offers outstanding circuit protection while allowing straightforward installation onto standard DIN rails within switchboards and control panels.
The ABB S203P-C4 combines delayed thermal overload protection with instantaneous magnetic short circuit protection to ensure dependable operation under normal conditions while rapidly disconnecting fault currents. This helps protect electrical equipment, reduce downtime and improve system reliability.
Designed for professional electrical installations, the S200P range offers high breaking capacity, compact dimensions and compatibility with ABB auxiliary contacts and accessories, making it an excellent choice for industrial automation, machinery and power distribution systems.
