EVS 800-1600 Low-voltage Vacuum Contactor
EVS 800-1600 Low-voltage Vacuum Contactor
EVS(800-1600)/1140 mndandanda otsika voteji vacuum contactor ndi mzati structural unit limodzi, akhoza kusonkhana n mizati malinga ndi zofuna za kasitomala.Njira yake yogwiritsira ntchito ndi electromagnetic holding, DC magnetic system.Mukamagwiritsa ntchito gwero lamagetsi la AC, limapereka DC kuti ipitirire kudzera pa chowongolera.Pansi pa AC-1, AC-2 kalasi yogwiritsira ntchito, ndiyoyenera nthawi zomwe zimafunikira kuwongolera kwakanthawi.
