EVC5-7.2/12-160/250/400/630
EVC5-7.2,12/160,250,400,630 series vacuum contactor is used in an AC. 50-60 Hz electric power system, with rated working voltage is 7.2Kv and 12kV, and rated current of 160A, 250A, 400A,630A, for direct or remote on-off control and circuit-breaking control of the of the main load. It is especially suitable for the frequently operated electric control applications such as electric motors, transformer, etc.
Working conditions
- Ambient temperature: Maximum ambient air temperature not exceeds 40℃; averaged air temperature within 24 hours not exceeds 35℃; Minimum ambient temperature to be not lower than -15℃. If the ambient temperature exceeds 40℃, the contactor should be used with lower capacity and need to be proved. The highest temperature of the contactor should not exceed 105℃.
- Altitude above sea level: altitude above sea level of the installation place not exceeds 1,000 m.
- Relative humidity: relative humidity of the atmospheric air not exceeds 50% when the ambient air temperature is 40℃; higher relative humidity is allowed when the air temperature is lower, daily averaged relative humidity not exceeds 95%; maximum monthly averaged relative humidity is 90% when the averaged air temperature is 20℃ in most humid months. Having taken into account the condensation dew on the surface of the product due to the temperature variation.
- Installation conditions: inclination angle of the installed plane with the vertical plane not exceeds 5°.
- Contamination class: class III
