Lead-in distributors LID, LID1 are designed (according to panel’s type) to receive, distribute and count electrical energy of the three-phase alternating current with the voltage of 380-220 V of 50 Hz frequency. It is also used to prevent the lines from the short circuits. The device is designed to be installed in the buildings with electrical control units. They are produced for one-side usage and designed for exploitation in the living apartments, municipal and civil buildings. The usage of the device in different places is also possible if they have similar energy saving scheme.

The nominal working regime is long-lasting.

The design

Lead-in distributors are produced in the floor-level models. These switchboards have wireframe enclosure covered from the top and from the sides with removable boards. The door is locked down. The complete equipment is installed into panel’s enclosure. There is a zero bus with clips for connection of the zero conductors of in-coming and out-going lines in the inferior part of the enclosure. The grounding of the enclosures is provided by the connection of the zero conductors of the supplying cables or wires to the zero bus (it is connected electrically with the enclosures of all panels). The lead-in of cables and wires is made from the bottom. The accounting equipment (counters and current transformers) are installed in the separate panel’s section. We can install either induction or electronic counters. The equipment for automatic and manual lights control is also in the separate section. The equipment installed in one panel but fed from different lead-ins is separated by barriers. Lead-in clips assume the connection of wires and cables with aluminium conductors with the cut up to 2х95 mm2 or 1x240 mm2for each lead-in position. The device is completed with breaker of ВР32 series; with current transformers of Т-0.66 series; protective devices of ППН-33, ППН-35, ППН-37 series (direct-voltage transducers); automatic switchers of RI (PR) series. According to client’s demand the excess-voltage suppressors of B class can be installed onto the lead-ins. We assume the change of the listed equipment without the degradation of product’s quality. Lead-in distributors LID, LID1 are mounted through four holes in the base of each frame. It is possible to connect the close-by frames with the bolts if these side walls are deinstalled.
