Features of JCZ5 series vacuum contactor

1. High reliability: The vacuum contactor has almost no wear when breaking the arc, ensuring stability during high-frequency operation.
2. Long life: The vacuum interrupter has a longer service life, a long maintenance cycle, and reduces operating costs.
3. Low maintenance requirements: Since the internal components are in a vacuum, the impact of external factors such as oxidation and corrosion on the equipment is reduced.

Normal working conditions

1) Altitude above sea should not be over 1,000m;

2) Ambient temperature is -5°C~+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
