Manual Mechanical Interlocking System
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.
