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