Voltage Change Switches

General Details

Voltage Change Switches

Voltage Change Switches are rugged voltage changeover switches designed for the generator industry. Custom design is available for any application.

Voltage Change Switches offer the advantage of not having to do any rewiring, simply having to only turn the handle for operation.

A changeover switch is used during an outage. It is designed to transfer electricity from the commercial power grid to a local generator. Therefore, when the end user is experiencing a power cut, the generator from the changeover switch will provide power

Whether it’s a Kohler, Cummins, Caterpillar, Magnetek, Katolight, Generac, Leroy Somer, Marathon, Marelli, Meccalte, Weg, or another manufacturer, a switch can be designed for your application. These units have a rugged durable design especially suitable for the generator industry.

To order, simply give us the hookup you require, (Wye, Wye-wye, Delta, Double-delta, Zig–zag), the KW rating and the generator manufacturer and our experienced engineers will design a high quality switch around the hook-up of your generator. Please see attached specification sheets for more info.
