£134.18
The ABB 2CDS382001R0117, also designated S302P-K0.3, is a high-performance 2-pole miniature circuit breaker (MCB) from the established ABB System pro M compact S300P series. It provides reliable overload and short circuit protection for specialised industrial, commercial and OEM electrical installations requiring sensitive low-current protection and high breaking capacity.
Manufactured in accordance with international IEC and UL standards, the S302P-K0.3 features a compact DIN rail mounted design, clear contact and trip indication, and ABB fail-safe terminal technology for secure installation. Its K tripping characteristic is designed for inductive loads and equipment that can produce relatively high starting currents during normal operation.
With a 0.3 A rated current, 2-pole configuration, operating voltage of up to 415 V AC and a breaking capacity of up to 25 kA to IEC/EN 60898-1, the ABB S302P-K0.3 is suitable for protecting low-current control, automation and instrumentation circuits in demanding electrical systems.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit conditions occur. This helps prevent conductor overheating, insulation damage and equipment failure while supporting safer and more reliable electrical installations.
The K tripping characteristic is commonly used for inductive circuits where temporary starting currents may occur during normal operation. This allows the S302P-K0.3 to provide dependable overload protection while reducing the risk of unwanted tripping when compatible transformers, relays, solenoids or other inductive devices are energised.
