EVS 800-1600 Yakaderera-voltage Vacuum Contactor
EVS 800-1600 Yakaderera-voltage Vacuum Contactor
EVS(800-1600)/1140 yakatevedzana yakaderera-voltage vacuum contactor imwe danda rechimiro unit, inogona kuungana kune n mapango zvinoenderana nezvinodiwa nemutengi.Iyo yekushandisa kwayo ndeye electromagnetic kubata, DC magineti system.Paunenge uchishandisa AC control magetsi sosi, inopa DC kuti coil kuburikidza nekugadzirisa.Pasi pe AC-1, AC-2 kirasi yekushandisa, inokodzera zviitiko zvinoda kutonga-kwazvino.
