ZJWTP100DE DC contactor for electric winch - ZJWTP100DE DC contactor for electric winch Application of ZJWTP100DE DC contactor for electric winch: ZJWTP100DE DC contactor for electric winch is used in electric winch supporting motorcar, with high and low voltage resistant and waterproof features. AC Mechanically Interlocked IEC Contactors Mechanically interlocked contactors, like the ones pictured above, are designed for reversing 2 speed, reduced voltage, type starter applications. Safety Contactors. So this protection device can be used in power circuit. Results shown in this section summarize the electromagnetic and mechanical behavior of the AC and DC contactors dealt with in this work. it is mainly used for the switching power of motors. Our products include Battery Connector, DC Contactor, DC converter, Tiller Head, Speed Controller, Ignition Switch,LED Strobe Beacon, LED Work Light. DC Power Contactor 200A, Coil 12V - Powerful electrically operated switch designed for DC voltage with a maximum current 200A. So, a DC motor is started by using a starter. In dc contactors their operating voltage is 24vdv and in AC contactors operating voltage is 230V or 415V. The coil of the contactor can be 24, 115, or 230 V, and even higher depending on the application. DC Contactors Trombetta builts several different industrial DC contactors for use in a variety of applications. on Contactors and Motor Starters. 0 Class: Contactors and Motor.
