£89.41
The ABB S203M-D3 is a compact and 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, current limiting performance and professional DIN rail installation.
With a 3 A rated current and D tripping characteristic, the S203M-D3 is suitable for circuits with high inrush currents, including transformers, solenoids, control circuits and specialist industrial equipment. Its 3-pole configuration provides coordinated protection across three-phase circuits.
The ABB S203M-D3 combines a robust modular housing, secure screw terminals and a high 10 kA breaking capacity. This makes it a reliable choice for control panels, distribution boards and machinery installations where dependable protection and compact installation are required.
Miniature circuit breakers such as the ABB S203M-D3 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 D characteristic is designed for circuits with high starting currents, making the S203M-D3 suitable for transformers, solenoids, power supplies and other inductive equipment where short-duration inrush current is expected.
