£58.55
The ABB 2CDS381001R0217, also known as the S301P-C40, is a high-performance single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is engineered to provide reliable protection against overloads and short circuits in industrial and commercial electrical installations where high fault interruption capability is essential.
The S301P-C40 combines thermal overload protection with electromagnetic short-circuit protection. Its Type C tripping characteristic is designed for circuits supplying equipment with moderate inrush currents, making it suitable for motors, transformers, power supplies and industrial control equipment.
With a 40 A rated current, a compact single-pole configuration and a 25 kA short-circuit breaking capacity, the ABB 2CDS381001R0217 delivers dependable circuit protection while offering straightforward DIN rail installation and long service life.
The ABB S301P-C40 automatically disconnects electrical circuits during overload and short-circuit conditions, protecting electrical wiring, machinery and connected equipment from damage. Its thermal trip responds to prolonged overloads, while its magnetic trip reacts almost instantly to fault currents.
The Type C characteristic is designed to tolerate moderate temporary inrush currents, making this breaker particularly suitable for industrial machinery, transformers, motor circuits and commercial electrical distribution systems.
