£48.11
The ABB S301P-K8 (2CDS381001R0407) is a high-performance single-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial electrical installations. As part of the proven ABB S300P series, it offers exceptional breaking capacity and reliable operation for machinery, control panels and industrial power distribution systems.
Featuring a K tripping characteristic, the S301P-K8 is specifically designed for circuits supplying motors, transformers, solenoids and other inductive loads with higher inrush currents. Its robust thermal and magnetic trip mechanisms deliver dependable protection while minimising nuisance tripping during equipment start-up.
With a rated current of 8 A, single-pole configuration and DIN rail mounting, this miniature circuit breaker is ideal for industrial control panels, automation equipment, OEM machinery and commercial electrical installations requiring reliable circuit protection.
Miniature circuit breakers automatically disconnect electrical circuits when overloads or short circuits occur, helping protect wiring, machinery and connected equipment from electrical damage. Their resettable design enables rapid restoration of service once faults have been resolved.
The K tripping characteristic is ideal for applications with high inrush currents, allowing motors and transformers to start normally while still providing dependable fault protection. This makes the ABB S301P-K8 particularly suitable for industrial automation and machine-building applications.
