Product Description

describe:

CKG3-12 series high-voltage vacuum AC contactors are suitable for long-distance connecting and breaking lines and frequent starting in power networks with AC 50-60Hz, rated working voltage of the main circuit 12KV, and rated current below 630A. It is suitable for controlling AC motors, and is more suitable for replacing vacuum circuit breakers with fuses and various protection devices.

Application environment conditions:
1. The ambient air temperature is not higher than +40°C and not lower than -10°C; 2. The altitude of the installation site is not more than 1,000 meters for ordinary models, and not more than 4,000 meters for plateau models; 3. The relative humidity of the air, the wettest month The average maximum relative humidity is 90%, and the average minimum temperature of the month is 25°C, and the condensation on the product surface due to humidity changes is considered; 4. Occasions without obvious shaking and shock vibration. 5. There is no explosion hazard, and there is no gas and dust (including conductive dust) that can corrode the insulation; 6. A place without rain and snow.
