Induction Furnace Resistor Insertion Switch Control

Control Voltage Control Part No.
120 VAC 1003248G1

This control operates two 15 kV 600 A three pole switches in a resistor insertion switch arrangement for transient in-rush control. The control first closes one switch through 80 ohm resistor modules. One hundred milliseconds later the control closes a second switch bypassing the resistors.

To Arc Furnaces 15kV or 15 MVA and Less
