7.2kV 12kV Hot Sales High Quality 3 phase AC electromagnetic electric vacuum contactor

Application:

The JCZ5-7.2 and JCZ5-12 series indoor AC high voltage vacuum contactor, it is divided into closing mechanical keeping and electromagnetic keeping two forms. This contactor is suitable for three phase AC 50Hz,rated voltage 7.2kV and 12kV,rated current up to 630A electricity power system, for long-distance making and breaking circuit, control such as the high voltage motor, transformer and capacitive load electrical equipment, especially suitable for the frequent operation. This contactor has the small shape,light weight, the assembled structure adopts the international popular layout of packaged up and down, convenient use and maintenance.

 

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
