£134.18
The ABB 2CDS382001R0157, also designated S302P-K0.5, is a high-performance 2-pole miniature circuit breaker (MCB) from the proven ABB System pro M compact S300P series. It is designed to provide dependable overload and short circuit protection for industrial, commercial and OEM electrical installations requiring sensitive low-current protection with exceptional breaking capacity.
Manufactured in accordance with international IEC and UL standards, the S302P-K0.5 features a compact DIN rail mounted design, integrated contact and trip indication, and ABB fail-safe terminal technology for secure installation. Its K tripping characteristic is specifically intended for inductive loads with high starting currents, making it ideal for protecting motors, transformers, relays and specialised control equipment.
With a 0.5 A rated current, 2-pole configuration, operating voltage up to 415 V AC and a breaking capacity of up to 25 kA to IEC/EN 60898-1, the ABB S302P-K0.5 delivers reliable protection for sensitive industrial control and automation circuits.
Miniature circuit breakers automatically disconnect electrical circuits during overload and short circuit conditions, helping protect wiring, control equipment and connected devices while improving operational safety and system reliability.
The K tripping characteristic is particularly suitable for inductive loads that generate high inrush currents during start-up, allowing reliable operation without unnecessary nuisance tripping while maintaining dependable overload protection.
