Allen-Bradley - Contactor 7kV 800A 1-2000M Fas - 1502-V8DXDD-2

IntelliVAC control (series E). The electrically held vacuum contactor with fast drop-out time operates as follows: When the IntelliVAC and IntelliVAC plus control modules receive a close command, the contactor coil is energized, the current creates an electromagnet in the coil. The electromagnet pulls the armature plate towards the coil core, rotating the shaft and causing the actuator plate to move upwards. As the actuator plate moves, it pushes the insulator and movable shaft up, closing the contacts in the vacuum bottle. The IntelliVAC and IntelliVAC plus control modules supply the close current to the coil for approximately 200 milliseconds. Afterward, the coil current is reduced to a lower hold-in value. When the IntelliVAC and IntelliVAC plus control modules have the close command removed, the coil is de-energized, opening the contactor.
