Why Choose the ABB 2CDS381001R0277 Miniature Circuit Breaker?
The ABB 2CDS381001R0277, also known as the S301P-K2, 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 and control equipment require a specialised Type K tripping characteristic.
The Type K characteristic is specifically intended for circuits with high inrush currents while still providing rapid protection against short circuits. This makes the S301P-K2 an excellent choice for industrial automation, motor control, transformers, solenoids and inductive loads where conventional Type B or Type C breakers may nuisance trip.
With a 2 A rated current, a compact single-pole design and a 25 kA rated short-circuit breaking capacity, the ABB 2CDS381001R0277 delivers outstanding protection whilst occupying only one DIN module, making it ideal for modern industrial control panels and OEM machinery.

Reliable Type K Circuit Protection
The ABB S301P-K2 automatically disconnects circuits during overload and short-circuit conditions, protecting motors, transformers, contactors and other inductive equipment from electrical faults. The thermal release protects against sustained overloads, while the magnetic release provides rapid fault interruption.
The Type K characteristic is specifically developed for inductive loads that experience high starting currents. It reduces unnecessary tripping whilst maintaining dependable protection for industrial machinery and automation equipment.
