£58.55
The ABB 2CDS381001R0187, also known as the S301P-K0.75, is a premium single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is engineered to provide dependable protection against overloads and short circuits in industrial electrical installations where high breaking capacity and precise protection are essential.
Designed for industrial control panels, machinery and automation systems, the S300P range combines thermal and magnetic tripping technology with robust construction to deliver reliable circuit protection. Its compact DIN rail design allows quick installation while maintaining full compatibility with ABB System pro M compact accessories.
With a 0.75 A rated current, a Type K tripping characteristic and a 25 kA rated short-circuit breaking capacity, the ABB 2CDS381001R0187 is ideally suited to protecting circuits with motors, transformers and inductive loads where higher inrush currents occur.
Miniature circuit breakers automatically disconnect electrical circuits during overload or short-circuit conditions, helping to protect wiring, machinery and connected equipment. Their resettable design reduces maintenance while improving electrical system reliability.
The Type K characteristic is specifically intended for circuits with higher inrush currents, making the ABB S301P-K0.75 particularly suitable for motor control circuits, transformers, solenoids and other inductive industrial loads requiring dependable protection without nuisance tripping.
