£134.18
The ABB S302P-K1 (SKU: 2CDS382001R0217) is a premium 2-pole miniature circuit breaker (MCB) engineered to provide reliable overload and short-circuit protection for industrial control circuits and demanding electrical installations. As part of the proven ABB System pro M Compact S300P series, it delivers high-performance circuit protection with a high fault interruption capability for industrial applications.
Designed for long service life, the S302P-K1 combines thermal overload protection with fast magnetic short-circuit protection to safeguard electrical equipment, motors and distribution systems. Its compact modular construction allows easy installation on standard DIN rails within switchboards, distribution boards and industrial control panels.
With a 1 A rated current, K tripping characteristic, 2-pole configuration and a 25 kA breaking capacity, the S302P-K1 is ideally suited for protecting circuits supplying motors, transformers and other inductive loads where higher inrush currents are expected.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur. The ABB S302P-K1 combines thermal overload protection with rapid magnetic tripping to minimise equipment damage, improve electrical safety and reduce costly downtime in industrial environments.
Its K tripping characteristic is specifically intended for circuits with higher inrush currents, making it particularly suitable for protecting motors, transformers, contactors and other inductive loads while maintaining dependable fault protection.
