Description
Lead-in distribution empty enclosuresare intended for electric power supply, accounting and distribution with 380/220 V voltage in three-phase AC networks (frequency - 50 Hz) as well as for protecting the lines at short circuits and overloads. They are also designed for often operation actuation and power-offs.
VRU metal empty enclosure is noted for its dismountable construction consisting of lateral frames installed on a base and connected with buckles. Lateral frames host a door, rear panel and top. Dismountable side panels help to reduce the expenses when assembling the empty enclosures into blocks. Cabling and wiring is organized below the empty enclosure.
