Manual Mechanical Interlocking System

Interlocking System

LV426909

Some installations use two power supply sources to counter any temporary loss in the main supply. A mechanical interlocking system is required to safely switch between the two sources. The replacement source can be a generator set or another network.

The mechanical interlocking system is made up of:

  • two B-frame devices

  • mechanical interlock, which prevents handle movement of one device from the OFF position while the other device is in the ON position.

Available as field-installable kit LV426909.
