Why Choose the ABB S202-C4 Miniature Circuit Breaker?
The ABB S202-C4 is a premium two-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in residential, commercial and industrial electrical installations. As part of the renowned ABB System pro M Compact S200 series, it offers reliable current limiting, compact dimensions and long-term operational performance.
The S202-C4 incorporates both delayed thermal and electromechanical tripping mechanisms. The thermal element protects against sustained overloads, while the magnetic trip rapidly disconnects short-circuit faults to help protect electrical wiring and connected equipment. The modular design also supports bottom-mounted auxiliary contacts, helping to optimise space inside electrical enclosures.
With a 4 A rated current, C curve tripping characteristic, two-pole configuration and a 6 kA rated breaking capacity, the ABB S202-C4 is ideal for protecting control circuits, lighting installations, instrumentation, automation equipment and other low-current electrical applications requiring dependable circuit protection.
