Why Choose the ABB 2CDS381001R0255 Miniature Circuit Breaker?
The ABB 2CDS381001R0255, also known as the S301P-B25, 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 commercial and industrial electrical installations while offering a high fault interruption capability for demanding applications.
The S301P-B25 combines thermal overload protection with electromagnetic short-circuit protection. Its Type B tripping characteristic is designed for circuits with low inrush currents, making it particularly suitable for lighting installations, socket outlets, resistive loads and general-purpose electrical distribution systems.
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 2CDS381001R0255 delivers dependable protection while occupying only one modular space. Fail-safe terminals, DIN rail mounting and clear contact indication simplify installation and maintenance.

Reliable Type B Circuit Protection
The ABB S301P-B25 automatically disconnects electrical circuits during overload and short-circuit conditions, helping to protect wiring, switchgear and connected equipment from damage. The thermal release responds to prolonged overloads, while the electromagnetic release rapidly interrupts fault currents.
The Type B characteristic trips magnetically between three and five times the rated current, making it ideal for circuits with low inrush currents such as lighting installations, heating circuits, socket outlets and general-purpose electrical distribution systems.
Typical Applications
- Commercial distribution boards.
- Industrial electrical installations.
- Lighting circuits.
- Socket outlet circuits.
- Resistive heating loads.
- Building services installations.
- Control panels.
- General-purpose electrical distribution.
