Why Choose the ABB 2CDS381001R0317 Miniature Circuit Breaker?
The ABB 2CDS381001R0317, also known as the S301P-K3, is a premium single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is designed to provide dependable protection against overloads and short circuits in industrial electrical installations where motors, transformers, contactors and other inductive loads require a specialised Type K tripping characteristic.
The Type K characteristic is specifically developed for circuits with high inrush currents while still providing rapid short-circuit protection. This makes the S301P-K3 particularly suitable for industrial automation, motor control panels, transformers, solenoid circuits and OEM machinery where nuisance tripping must be minimised.
With a 3 A rated current, compact single-pole construction and a 25 kA rated short-circuit breaking capacity, the ABB 2CDS381001R0317 delivers reliable protection whilst occupying only one DIN module, making it ideal for modern industrial control panels and electrical distribution systems.

Reliable Type K Circuit Protection
The ABB S301P-K3 automatically disconnects electrical circuits during overload and short-circuit conditions. Its thermal release protects against sustained overloads, whilst its magnetic release provides rapid interruption of fault currents, helping to protect motors, transformers, contactors and other inductive equipment.
The Type K tripping characteristic is designed specifically for industrial loads with high starting currents. This allows temporary inrush currents without unnecessary tripping while maintaining dependable protection for industrial machinery and automation systems.
Typical Applications
- Motor control circuits.
- Industrial automation systems.
- PLC control panels.
- Transformers.
- Solenoid circuits.
- OEM machinery.
- Industrial control equipment.
- Electrical distribution systems.
