Type HS for both direct (DC) and alter- nating current (AC) can be used as polarity-independent circuit-breakers in electric traction vehicles. They are used primarily as heating contactors, filter capacitor precharging contactors and as contactor relays in auxiliary cir- cuits.The contactors have been spe- cially designed for use under the extre- mely harsh operating conditions encountered with electric traction vehicles and for particularly high switching rates. Other main features are their space-saving design, large insulation distances and minimum maintenance requirements. This type of contactor...
