CKG3-12kv 160A,250A,400A,630A AC Three Pole H.V Vacuum Contactor

Item No: CKG3-12kv

Application:

CKG3/-12 AC vacuum contactors (hereinafter referred to as: contactor) are applied in power network with AC frequency of 50Hz-60Hz, rated voltage of 12kV, and rated current below 630A in the main loop for the remote making and breaking, frequent start and control of AC motor. It is advisable to use them in combination with fuse and protective device to replace vacuum circuit breaker.

Normal working conditions:

1) Altitude above sea should not be over 1,000m; 2) Ambient temperature is -5~40°C; 3) Average temperature in 24 hour limited below 35°C; 4) When the highest temperature is 40°C, the relative humidity should not be higher than 50%; 5) Pollution degree: class 3
