Why Choose the ABB S202-C20 Miniature Circuit Breaker?
The ABB S202-C20 is a dependable two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the established ABB System pro M Compact S200 series, it provides reliable current-limiting protection for residential, commercial and industrial electrical installations.
The S202-C20 uses two complementary tripping mechanisms. A delayed thermal mechanism responds to sustained overload conditions, while an electromechanical mechanism provides rapid disconnection during short-circuit faults. This combination helps protect cables, connected equipment and electrical distribution systems during normal operation and fault conditions.
With a 20 A rated current, a C curve tripping characteristic, a two-pole configuration and a 6 kA rated breaking capacity, the ABB S202-C20 is suitable for general-purpose circuits with moderate starting currents. Typical applications include lighting, socket outlets, HVAC equipment, small motors, control systems and commercial distribution boards.

Reliable Protection for General Electrical Circuits
The ABB S202-C20 automatically disconnects an electrical circuit when an overload or short circuit occurs. Its thermal tripping mechanism responds to prolonged overcurrent, while the electromagnetic mechanism rapidly interrupts high fault currents to help minimise damage to wiring and connected equipment.
The C curve characteristic provides a practical balance between protection sensitivity and tolerance of temporary starting currents. This makes the S202-C20 suitable for correctly designed circuits supplying lighting, socket outlets, HVAC equipment, small motors, transformers and other general-purpose electrical loads.
Typical Applications
- Residential consumer units.
- Commercial distribution boards.
- Lighting circuits.
- Socket outlet circuits.
- HVAC and ventilation equipment.
- Small motors and pumps.
- Industrial control panels.
- OEM machinery and automation systems.
