£109.42
The ABB S203M-D16 is a robust 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 delivers high breaking capacity, current limiting performance and compact DIN rail installation for professional distribution systems.
With a 16 A rated current and D tripping characteristic, the S203M-D16 is suitable for circuits with high inrush currents, including motors, transformers, solenoids and industrial equipment. Its 3-pole configuration provides coordinated protection across three-phase circuits.
The ABB S203M-D16 combines a durable modular housing, secure screw terminals and a high 10 kA breaking capacity. This makes it a dependable choice for control panels, distribution boards and machinery installations where safe, consistent and standards-compliant circuit protection is required.
Miniature circuit breakers such as the ABB S203M-D16 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-D16 suitable for motors, transformers, solenoids and other inductive equipment where short-duration inrush current is expected.
