12kv Sealed Structured High Voltage AC Indoor Vacuum Circuit Beaker

NINGBO TIANAN (GROUP) CO., LTD.
 

General

VT19-12 indoor HV vacuum circuit breaker is used in three-phase AC electric system of 50HZ,12kV. It is used as control and protection department in the mining company ,power factory and substation. Because of its special advantages, it is also suitable for the site which frequently operation under rated current or multiple breaking short-circuit current.

The circuit breaker is identified by some national standards and international relative standards, such as GB1984,GB/T11022,DL/T403 and IEC62271, etc. It has reliable lockage, used as truck department or fixed installation department.
