The ABB System pro M compact S204-C16 (ABB catalog number 2CDS254001R0164) is a 4-pole miniature circuit breaker rated 16A with a Type C tripping characteristic, built on the same S200 platform as ABB's standard MCB range. The Type C curve gives an instantaneous trip band of 5 to 10 times the rated current, wider than a Type B breaker, which is why it is generally specified for circuits with higher inrush currents at switch-on — three-phase motor starters, transformers, and fluorescent or LED lighting banks — where a Type B unit would be prone to nuisance tripping.

Rated for 400V AC on the IEC side and 110V DC on the UL/CSA rating, this unit carries a 6 kA short-circuit breaking capacity (Icn), covering typical distribution board fault-current levels. It complies with BS EN 60898 and uses finger-safe terminals, so live parts stay shielded during panel wiring and maintenance — a standard requirement for boards accessible to site electricians.

As a 4-pole unit, it switches and protects all phases plus neutral in a single device, which is the usual specification for three-phase distribution circuits where the whole circuit needs to be isolated together rather than per-phase. Like the rest of the System pro M compact S200 range, it is a current-limiting, DIN-rail mounted breaker designed for standard distribution boards and control panels.
