Acti 9 C120

Miniature Circuit Breakers up to 125 A

Part of 9 Series

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

Acti 9 C120
  • Features

    Acti 9 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
    • IP20 terminal insulation
    • Optional add-on residual current device modules: C120 Vigi
    • Optional electrical auxiliaries for remote Open/closed status or remote tripping of 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 ratings applications
