Product Description
1.Product introduction
This vacuum contactor is suitable for AC 50~60Hz,rated voltage of the main circuit 1.14kV~2kV,the main circuit rated current from 1000A to 2000A power network system for remote making and breaking and frequent starting and controlling AC motors,transformers and capacitor banks and other occasions.This series vacuum contactor adopts the fully enclosed structure,large capacity heat dissipation and high performance components,has the advantages of stable and reliable mechanical properties,long service life,maintenance-free and so on.
2.Product normal working conditions
2.1.Ambient temperature -40ºC ~ +60 ºC.
2.2.Installation site altitude does not exceed 3000m.
2.3.The relative humidity of the air does not exceed 50% at a maximum temperature of +60 degrees.At a relatively low temperature,when the relative humidity is relatively high,for example,the monthly minimum humidity of the wettest month is +25 degrees,the average monthly maximum humidity is 90%,taking into account the frost that occurs on the surface of the product due to temperature changes.
