£113.04
The ABB S203M-C1 is a compact and reliable 3-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in residential, commercial and industrial installations. Part of the proven ABB System pro M Compact S200M series, it delivers dependable circuit protection for modern distribution boards, control panels and OEM equipment.
Featuring a Type C tripping characteristic, the S203M-C1 is suitable for circuits with moderate inrush currents, including small transformers, control circuits, instrumentation supplies and selected inductive loads. Its current-limiting design helps reduce fault energy while supporting safe and reliable operation.
With a 1 A rated current, 3-pole configuration and 10 kA breaking capacity, the ABB S203M-C1 is ideal for protecting low current three-phase circuits where compact installation, ABB quality and standards-compliant performance are required.
The ABB S203M-C1 automatically disconnects electrical circuits when overload or short-circuit conditions occur. This helps protect control wiring, auxiliary supplies, switchgear and connected equipment from damage caused by excessive current.
Its Type C characteristic makes it suitable for circuits where temporary start-up inrush may occur, while its 3-pole design allows simultaneous protection and disconnection across three conductors. The S200M series is widely used by professional installers due to its compact format, current-limiting performance and accessory compatibility.
