ABB S301P-K6 single-pole miniature circuit breaker with a 6 A rated current, K tripping characteristic and high breaking capacity for industrial overload and short-circuit protection.
£48.11
The ABB S301P-K6 (2CDS381001R0377) is a high-performance single-pole miniature circuit breaker (MCB) designed to protect industrial electrical circuits against overloads and short circuits. As part of the advanced ABB S300P series, it combines a compact modular design with a high breaking capacity for dependable protection in demanding electrical installations.
This miniature circuit breaker features a K tripping characteristic, making it particularly suitable for circuits supplying motors, transformers, control equipment and other inductive loads with elevated starting currents. Its thermal and magnetic tripping mechanisms provide automatic circuit interruption when unsafe current conditions are detected.
With a 6 A rated current, single-pole configuration and standard DIN rail mounting, the S301P-K6 is ideal for industrial control panels, machinery and electrical distribution systems. Its narrow 17.5 mm modular width helps conserve valuable panel space while supporting straightforward installation and maintenance.
Miniature circuit breakers automatically disconnect an electrical circuit when an overload or short circuit occurs. This helps prevent excessive conductor temperatures, equipment damage and potential electrical hazards while allowing the circuit breaker to be reset after the fault has been corrected.
The K tripping characteristic is designed to tolerate the temporary starting currents associated with motors, transformers and solenoids while still providing effective fault protection. This makes the ABB S301P-K6 a practical solution for industrial automation systems and machinery containing inductive electrical loads.
