Product Details

Acti9 C120 

CHINT Made In China

AC Use Miniature Circuit Breakers 63~125A, 

 

Miniature Circuit Breakers for AC Current circuits, offering terminal distribution installation protection

 

C120H circuit breakers are multistandard circuit breakers that combine the following functions:
- Protection of cables against overloads and short-circuits in final distribution
- Manual control and isolation
- Earth leakage protection when combined with a Vigi C120 module without temperature derating: compliance with EN 61009
- Remote tripping, indication, by adding auxiliaries common to the entire C65 range.

  • Compliant with IEC60898-1, IEC60947-2
  • Available in 1P, 2P 3P, 4P
  • C, D tripping curve
  • Up to 500V AC.

 

General rules for choosing MCB
Technicala data of the network at the point considered:
The earthing systems(TNS,INC),Shrot-circuit current at the circuit-breaker installatino point,which must always be less than the breaking capacity of this device,Networl normal voltage.

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

  • Features

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: 63 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.


 

Benefits

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.

Applications

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