Why Choose the ABB 2CDS381001R0204 Miniature Circuit Breaker?
The ABB 2CDS381001R0204, also known as the S301P-C20, is a high-performance single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is designed to protect industrial and commercial electrical installations against overloads and short circuits while providing the high fault-interruption capability required in demanding applications.
The S301P-C20 combines thermal overload protection with electromagnetic short-circuit protection. Its Type C tripping characteristic accommodates moderate starting currents, making it suitable for circuits supplying equipment such as small motors, transformers, fluorescent lighting and industrial control devices.
With a 20 A rated current, a compact single-pole configuration and a short-circuit breaking capacity of up to 25 kA, the ABB 2CDS381001R0204 provides dependable protection without occupying unnecessary panel space. Tool-free DIN rail mounting, a front-facing trip indicator and compatibility with System pro M compact accessories further simplify installation and maintenance.

Reliable Type C Protection for Equipment Circuits
The ABB S301P-C20 automatically disconnects the protected circuit when it detects a sustained overload or a high short-circuit current. Its thermal element responds to prolonged overcurrent conditions, while its electromagnetic mechanism provides rapid interruption during short circuits.
A Type C miniature circuit breaker is designed to tolerate higher temporary starting currents than a Type B device. This helps reduce nuisance tripping when energising equipment with moderate inrush currents while maintaining dependable protection for cables, machinery and connected electrical devices.
