ABB S203M-D32 three-pole miniature circuit breaker with a 32 A rated current, D curve tripping characteristic and 10 kA short-circuit breaking capacity for industrial and commercial circuit protection.
£109.42
The ABB S203M-D32 is a reliable three-pole miniature circuit breaker (MCB) from the trusted ABB System pro M compact S200M series. It is designed to provide dependable protection against overloads and short circuits in commercial, industrial and OEM electrical installations.
Featuring a D curve tripping characteristic and a 32 A rated current, the S203M-D32 is suitable for circuits with high inrush currents, including transformers, solenoids, power supplies and selected motor-related loads. Its current-limiting design helps reduce fault energy while protecting connected equipment and electrical wiring.
The ABB S203M-D32 is designed for standard DIN rail mounting inside distribution boards, switchboards and industrial control panels. Its compact modular housing, robust construction and compatibility with ABB System pro M accessories make it a practical choice for professional electrical installations.
The ABB S203M-D32 uses thermal and magnetic tripping mechanisms to protect electrical circuits from overload and short-circuit faults. The delayed thermal trip responds to sustained overloads, while the electromechanical magnetic trip provides rapid disconnection during short-circuit conditions.
Its D curve characteristic is designed for applications where higher starting currents are expected. This helps reduce nuisance tripping during energisation while maintaining effective protection for cables, equipment and electrical installations.
