£91.07
The ABB S302P-B32 (SKU: 2CDS382001R0325) is a premium 2-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for industrial and commercial electrical installations. As part of the trusted ABB System pro M Compact S300P series, it offers reliable circuit protection and high performance for demanding applications while complying with international IEC and UL standards.
The S302P-B32 combines thermal overload protection with rapid magnetic short-circuit tripping to safeguard electrical distribution systems, lighting circuits and connected equipment. Its compact modular construction enables quick installation on standard DIN rails within distribution boards, switchboards and industrial control panels.
With a 32 A rated current, Type B tripping characteristic, 2-pole configuration and a 20 kA AC breaking capacity, the S302P-B32 is ideally suited for circuits with low inrush currents, providing dependable protection for resistive loads and general electrical distribution.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur. The ABB S302P-B32 combines thermal overload protection with rapid magnetic tripping to minimise equipment damage, improve electrical safety and reduce costly downtime in industrial and commercial environments.
Its Type B tripping characteristic is intended for circuits with relatively low inrush currents, making it particularly suitable for lighting installations, heating circuits, socket outlets, building services and general electrical distribution systems.
