£63.10
The ABB 2CDS381001R0218, also known as the S301P-C50, is a premium 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 while offering exceptional fault interruption capability for demanding applications.
Designed for switchboards, distribution boards and industrial control panels, the S301P-C50 combines thermal overload protection with electromagnetic short-circuit protection. Its Type C tripping characteristic makes it ideal for circuits supplying equipment with moderate inrush currents, including motors, transformers, power supplies and HVAC equipment.
With a 50 A rated current, a compact single-pole design and a 25 kA rated short-circuit breaking capacity, the ABB 2CDS381001R0218 delivers dependable protection, straightforward DIN rail installation and long-term operational reliability in demanding industrial environments.
The ABB S301P-C50 automatically disconnects electrical circuits during overload and short-circuit conditions, protecting wiring, electrical equipment and connected machinery from damage. Its thermal trip responds to sustained overloads, while the magnetic mechanism provides rapid interruption during fault-current events.
The Type C characteristic is intended for circuits with moderate temporary inrush currents, making it particularly suitable for industrial machinery, transformers, power supplies, HVAC equipment and commercial electrical distribution systems.
