Acti9 C120 Miniature Circuit Breakers

DIN rail Miniature Circuit Breakers (MCB) offering circuit protection against short-circuit and overload currents. Suitable for isolation in compliance with IEC 60947

Up to 125A

Product details


Acti9 C120 DIN rail, miniature circuit breakers offer extensive features that provide maximum safety and continuity of service while minimizing service and intervention time:

  • Nominal current: 10 to 125 A
  • Large choice of breaking capacities and tripping curves (B, C, D)
  • Compliant with IEC EN 60898 or IEC 60947-2 depending on the version
  • Suitable for isolation: compliant with IEC 60947
  • VisiSafe provides a visible green indicator showing which circuits are disconnected and safe for maintenance operations
  • Operating voltage: up to 440 V AC
  • Insulation voltage: 500 V AC
  • IP20 terminal insulation
  • Optional add-on residual current device modules: Acti9 C120 Vigi
  • Optional electrical auxiliaries for remote Open/closed status or remote tripping of Acti9 C120 circuit breaker with shunt, overvoltage, and Undervoltage release.


Longer product service life thanks to:

  • Good overvoltage withstand capacity: products are designed to offer a high industrial performance level (degree of pollution, rated impulse withstand voltage, and insulation voltage)
  • High limitation performances
  • Fast closure independent of toggle operating speed.


  • Protection of electrical circuits in all industrial and commercial buildings
  • Particularly suited to higher rating applications.
