Acti9 C120 Industrial Circuit Breaker 63A~125A, 1P,2P,3P,4P for Circuit Protection AC230V/400V Home or Industrial Use
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.
