ZN12-40.5ZN12-40.5manufacturers price _ type ZN12-40.5circuit breaker is a three-phase AC 50Hz, rated voltage 40.5kV indoor device.

ZN12indoor vacuum circuit breaker for 35kV50Hz three-phase alternating current power system, the circuit breaker arc extinguish chamber for ceramic structure, using a longitudinal magnetic field contact, has the advantages of small volume, open the diffused arc current on contact distribution unib, not partial melting phenomenon, also has a low voltage (20-200V ) and arc energy low cut off value (4-5A ), and with high reliability of the operating mechanism.

The circuit breaker adopts DYT-1 spring energy storage mechanism, can exchange energy storage or DC operation, can also be used to manually operation. The circuit breaker adopts a special contact material, so that the interrupter breaking capacity is higher, and has a long life.

The circuit breaker has the advantages of simple structure, strong breaking capacity, long service life, operation functions without the risk of explosion, repair is simple, applicable to power plants, substations and other electrical distribution system control and protection switch, especially for the breaking of heavy load and the place of frequent operation
