CKJ5-80-125-160-400-630-800 / 1.14KV Low-voltage vacuum contactors for AC 50HZ, rated voltage , 14KV. Rated current: 80-125-160-250-400-630-800A of Feed network. It is used to connect and disconnect circuits at a long distance and to frequently start and stop the AC motor. Unipolar is suitable for controlling street lights and other single switches. It is suitable to be assembled with various protection devices into an explosion-proof electromagnetic starter.
It is the most important circuit device in the industrial sectors such as coal, petroleum, chemical, metallurgy, machinery, transportation and electric power.
First, working conditions
1 . The altitude of the sea is not more than 2000 meters.
2 . Ambient air temperature: -25 to +40 °C .
3 . Relative humidity of air: Ambient air temperature does not exceed 50 % at +25 °C , and higher relative humidity at lower temperatures. When the average temperature of the wettest month is +25 °C , the monthly average maximum relative humidity is 90 %. 4 . The inclination of the mounting surface to the vertical surface does not exceed 15° . The installation category is usually category III . 5 . The environmental pollution level is level 3 . 6 . A field with a vibration of no more than 30 m / s.
