Why Choose the ABB S201-C4 Miniature Circuit Breaker?
The ABB S201-C4 is a compact single-pole miniature circuit breaker (MCB) from the established ABB System pro M compact S200 range. It is designed to protect low-voltage cables and circuits against overloads and short circuits using reliable thermal-magnetic tripping technology.
With a 4 A rated current and a Type C tripping characteristic, the S201-C4 is suitable for lower-current circuits that may experience moderate starting or inrush currents. Typical uses include industrial control circuits, automation equipment, instrumentation, signalling systems, small transformers and auxiliary power supplies.
The ABB S201-C4 offers a 6 kA rated short-circuit breaking capacity at 230/400 V AC under IEC/EN 60898-1. It also provides a 10 kA ultimate short-circuit breaking capacity under IEC/EN 60947-2, helping deliver dependable circuit protection across residential, commercial and industrial installations.
Key Advantages
- Reliable 4 A circuit protection for lower-current electrical loads.

Dependable Protection for Control and Auxiliary Circuits
The ABB S201-C4 combines two complementary tripping mechanisms. Its delayed thermal release responds to sustained overload conditions, while the electromagnetic release rapidly disconnects the circuit when a short circuit occurs.
The Type C characteristic accommodates moderate temporary inrush currents without unnecessary tripping. This makes the breaker particularly suitable for control panels and auxiliary circuits containing contactors, relays, small transformers, power supplies and other inductive components.
Typical Applications
- Industrial control panels.
- Building automation systems.
- Instrumentation circuits.
- Alarm and signalling equipment.
- Auxiliary power circuits.
- Small transformers and power supplies.
