Reliable AC/DC Circuit Protection
Miniature circuit breakers such as the ABB S202M-K0.3UC automatically disconnect a circuit when excessive current occurs as a result of an overload or short circuit. This helps protect cables, conductors and connected electrical equipment while allowing the circuit to be reset after the fault has been identified and corrected.
The S200 M UC series is specifically engineered for universal current applications and provides flexible protection for both alternating-current and direct-current circuits. Its K characteristic is well suited to circuits where normal operation can produce comparatively high starting or inrush currents, helping provide dependable protection while reducing unnecessary tripping.
Typical Applications
- DC and traction electrical systems.
- Industrial control and automation circuits.
- Low-current auxiliary circuits.
- Control panels and electrical distribution boards.
- Machinery and industrial equipment.
- Transportation and railway-related electrical systems.
