CJ19 series switching condenser contactor (hereinafter referred to as contactor) is mainly used in power lines with AC 50Hz (or 60Hz) and rated working voltage up to 400V, for low-voltage reactive power compensation equipment to put into operation or cut off low-voltage parallel capacitors. The contactor is equipped with a surge suppression device, which can effectively reduce the impact of the closing surge on the capacitor and suppress the overvoltage during disconnection.
Online InquiryWorking conditions
● Ambient temperature: -5℃~+40℃, the average value within 24 hours does not exceed +35℃;
● Altitude: no more than 2,000m;
● Atmospheric conditions: When the maximum temperature is +40℃, the relative humidity of the air does not exceed 50%; higher relative humidity can be allowed at lower temperatures, such as 90% at 20℃. Special measures should be taken for occasional condensation due to temperature changes;
● Pollution level: 3;
● Installation category: Category III;
● Installation conditions: The inclination between the installation surface and the vertical surface is not greater than ±5°;
● Impact and vibration: The product should be installed and used in a place without significant shaking, impact and vibration.
