£105.65
The ABB S203M-B6 is a dependable miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in residential, commercial and industrial electrical installations. Part of the ABB System pro M compact S200M series, it offers high breaking capacity, compact DIN rail installation and current limiting performance for professional distribution systems.
With a 6 A rated current and B tripping characteristic, the S203M-B6 is suitable for circuits with low inrush currents, including lighting, control circuits and general distribution applications. Its 3-pole configuration provides three-phase circuit protection, making it suitable for industrial panels, machinery and three-phase distribution boards.
The ABB S203M-B6 combines a compact modular housing, secure screw terminals and a high 10 kA breaking capacity. This makes it a reliable choice for electrical contractors, panel builders and engineers requiring safe, efficient and standards-compliant circuit protection.
Miniature circuit breakers such as the ABB S203M-B6 automatically disconnect electrical circuits when overload or short-circuit conditions occur. This helps protect cables, connected equipment and electrical installations from damage while supporting safer operation.
The B characteristic is designed for circuits with relatively low inrush currents, making the S203M-B6 well suited to lighting, control circuits and general distribution applications. Its 3-pole construction provides coordinated protection across three-phase electrical systems.
