Specific use vacuum contactor

Specific use vacuum contactor usually different from the generic class AC vacuum contactor,the generic class AC vacuum contactor is generally used in starting & breaking during operation(AC-3)of cage induction motors and(or) starting, reverse braking or reverse motion and inching (AC-4) of cage induction motors。 According to specific circumstances, it can also be used downstream in starting & breaking (AC-2) of wound rotor type induction motors, it can also be used in non-inductive or micro-inductive load and electric resistance furnace (AC - 1)。And you can use it in make-and-break of the transformers(AC-6a)and capacitor sets(AC-6b)。Business negotiations are welcome。 。

The vacuum contactor is generally designated to be used indoors, the general environmental conditions are as follows:

● Ambient temperature: The ambient air temperature should be no more than 40 ℃, in addition, the average temperature within 24 hours should be no more than 35 ℃, the ambient air temperature should be no less than-15 ℃.

● Height above sea level: As for altitude of the installation place. For low voltage type of switching elements and low-voltage in components among the high voltage switch components, it does not exceed 2000m, For high-voltage switch element it does not exceed 1000 m.

● Relative humidity: Relative humidity of the atmosphere does not exceed 50% at + 40℃ of the ambient air temperature. Under lower temperatures, a higher relative humidity is permitted, The daily average is no more than 95%. When in the wettest month, an average temperature is + 20 ℃. The mean monthly maximum relative humidity is 90%. Condensation due to temperature change occurred on the surface of products has been considered.

● Level of contamination: level III, with conductive pollution, Or the dry non-conductive pollution becomes conductive pollution due to condensation.
