£64.84
The ABB 2CDS381001R0607, also known as the ABB S301P-K63, is a high-performance miniature circuit breaker (MCB) from the trusted ABB System pro M compact S300P series. Designed for industrial electrical installations, it provides dependable protection against overloads and short circuits while meeting international IEC and UL standards for demanding applications.
Its robust thermal and magnetic trip mechanism ensures reliable fault protection, while the compact modular housing enables straightforward installation on standard DIN rails. The S301P series is widely used in industrial control panels, switchboards and OEM equipment where high breaking capacity and dependable operation are essential.
With a 63 A rated current, a Type K tripping characteristic and an ultimate breaking capacity of 25 kA, the ABB 2CDS381001R0607 is particularly suitable for circuits supplying motors, transformers and other inductive loads with higher inrush currents.
The ABB S301P-K63 automatically disconnects electrical circuits when overload or short-circuit conditions occur, helping protect wiring, machinery and connected equipment from damage. Its high interrupting capacity makes it suitable for installations where dependable fault clearance is critical.
The Type K tripping characteristic allows the breaker to accommodate the temporary inrush currents generated by motors, transformers and other inductive loads, reducing nuisance tripping while maintaining excellent circuit protection.
