CKG3 series AC high voltage vacuum contactors, is suitable for AC 50 ~ 60HZ, rated voltage of the main circuit 3.6KV 7.2KV, rated current from 160A to 1250A power network system for remote making and breaking and frequent starting and controlling AC motors, transformers and capacitor banks and other occasions .
2.The use of the environment conditions
2.1.Ambient temperature -25 ℃ ~ +40 ℃.
2.2.Installation site altitude does not exceed 2000m.
2.3.The relative humidity of the air , the wettest month average monthly maximum relative humidity of 90% , monthly average minimum temperature of 25 ° C,and taking into account the Cream of temperature changes on the surface of the product .
2.4.Environment:anhydrous invasion,non-corrosive and flammable gas and excessive vibration occasions .
3.1.Properly select the the contactor technology parameters , including auxiliary switch contacts are not overloaded .
3.2.Around and above contactor to leave enough space for insulation, to ensure the safety of use.
3.3.When you power up the control but there is no response, the power should be immediately cut off and check the reasons of control power,to avoid burnt out solenoid.
3.4.When the contactor is used to control inductive loads , recommended the the RC RC protection or varistor protection of overvoltage absorption protection device to protect the load security
3.5.When the electromagnetic system have strong magnetic attraction when it’s in working ,we should keep the things with ferromagnetic material away form the machine .
3.6.The contact device is not suitable carries on the series joining-up work
3.7.Main circuit connection principle : the upper end ( quiet side) into the line side , the lower end ( moving end ) is the outlet end .
