£84.04
The ABB S302P-B25 (SKU: 2CDS382001R0255) is a premium 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for industrial, commercial and OEM electrical installations. As part of the trusted ABB System pro M Compact S300P series, it delivers dependable protection in demanding environments where high fault interruption capability is essential.
Designed for long service life, the S302P-B25 combines thermal overload protection with rapid magnetic short-circuit protection to safeguard electrical equipment, distribution circuits and control systems. Its compact modular construction and DIN rail mounting allow straightforward installation in switchboards, distribution boards and industrial control panels.
With a 25 A rated current, Type B tripping characteristic, 2-pole configuration and a 25 kA breaking capacity, the S302P-B25 is ideally suited for circuits with relatively low inrush currents while providing exceptional fault protection for industrial electrical systems.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur. The ABB S302P-B25 combines thermal overload protection with rapid magnetic tripping to minimise equipment damage, reduce downtime and improve electrical safety.
Its Type B tripping characteristic makes it particularly suitable for circuits with relatively low inrush currents, including lighting, resistive loads and general electrical distribution systems, while its high 25 kA interruption rating provides excellent protection in installations with elevated prospective fault currents.
