Блок индикации напряжения LB-1R

A voltage indicating unit with a built-in relay, type: LB-1R is designed to work in tandem with a support insulator. It is a device for monitoring the presence or absence of voltage between the bus and the device body.
On the front panel of the unit there are three LEDs indicating the presence of voltage on each of the phases, respectively; also on the front panel there are three connectors that allow monitoring the connection of phases.
A relay built into the body of the unit allows, in the presence or absence of voltage between the bus and the body of the device, to implement the logic of operation of an electromagnetic blocking device or other device.
