ABB 2CDS381001R0254 S301P-C25 single-pole miniature circuit breaker with a 25 A rating, Type C tripping characteristic and 25 kA ultimate short-circuit breaking capacity.
£38.66
The ABB 2CDS381001R0254, also known as the S301P-C25, is a high-performance single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It provides reliable protection against overloads and short circuits in commercial and industrial electrical installations where a high fault-interruption capability is required.
The S301P-C25 combines thermal overload protection with electromagnetic short-circuit protection. Its Type C tripping characteristic is designed to accommodate moderate temporary inrush currents, making the breaker suitable for circuits supplying motors, transformers, power supplies, lighting systems and industrial control equipment.
With a 25 A rated current, a compact single-pole configuration and an ultimate short-circuit breaking capacity of up to 25 kA, the ABB 2CDS381001R0254 delivers dependable protection while occupying only one modular space. Dual DIN rail release, fail-safe terminals and clear contact and trip indication support efficient installation, operation and maintenance.
The ABB S301P-C25 automatically disconnects the protected circuit when a sustained overload or short circuit occurs. Its thermal release responds to prolonged overcurrent conditions, while its electromagnetic release rapidly interrupts severe fault currents to help protect cables, equipment and connected systems.
The Type C characteristic trips magnetically between five and ten times the rated current. This allows the breaker to withstand moderate starting currents without unnecessary tripping while maintaining reliable protection for industrial machinery, transformers, lighting equipment and building-services systems.

It protects commercial and industrial electrical circuits against overloads and short circuits, including circuits supplying equipment with moderate starting currents.
The ABB S301P-C25 has a rated current of 25 A.
A Type C breaker trips magnetically between five and ten times its rated current. This makes it suitable for motors, transformers, power supplies and other equipment that produces moderate inrush currents during start-up.
The ABB 2CDS381001R0254 has an ultimate short-circuit breaking capacity of up to 25 kA and a service breaking capacity of 12.5 kA under IEC/EN 60947-2 conditions.
Yes. The single-pole S301P-C25 is rated for operation at up to 72 V DC, subject to the applicable installation requirements and electrical standards.
It mounts onto a standard 35 mm DIN rail and can be supplied from either the top or bottom. Its fail-safe terminals accept cables and busbars through separate terminal openings.
ABB System pro M compact S300P miniature circuit breakers are specified by electrical engineers, OEMs and panel builders for their high breaking capacity, dependable operation, clear status indication and compatibility with internationally recognised electrical standards.
