Induction Furnace Resistor Insertion Switch Control

Control Voltage Control Part No.
120VAC 1003248G1

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

To Arc Furnaces 15kV or 15 MVA and Less
