Incoming Distribution Switchboards (VRP / VRU)
General information
An incoming distribution switchboard (VRP/VRU) is a low-voltage assembly for 0.4 kV (380/220 V, 50 Hz) installed where the supply cable enters the building: depending on the panel type it accepts the incoming power, meters it and distributes it to the loads, and protects the feeders against overload and short circuit. It works in networks with a solidly earthed neutral (TN-C, TN-C-S). Panel types are incoming, incoming-distribution and distribution — not every type includes metering. In the product passport the same unit is named «ввідно-розподільчий пункт» (incoming distribution point).
The devices are designed for installation in electrical switchgear rooms. Wire and cable entry/exit is provided from below. The devices are manufactured for single-sided (front) access and are intended for operation in residential, communal-domestic and public buildings. Use of the devices at other facilities with a similar power supply scheme is permitted.
The VRP switching apparatus is of air-type and moulded-case design (switch-disconnectors, ПН-2/ППН fuses, MCCB/ACB circuit breakers, current transformers). The specific composition and ratings are selected for the project as per the technical specification (TS).
- Rated operating mode — continuous.
- Climatic design — U3.
- Ingress protection IP31 per the set passports; IP00 from the bottom, as cables enter from below.
- Rated current of the assembly — to project; in delivered work, panels from 100 to 1600 A in a single set.
- Short-circuit withstand (Icw / Ipk) — to project.
The devices comply with DSTU EN 61439-1, DSTU IEC 60439-1 and the manufacturer's own technical specifications (TU). VRP units are manufactured to order per the technical specification; ratings, apparatus set and panel layout are determined by the project.

Description and purpose
An incoming distribution switchboard (VRP/VRU) 0.4 kV is the node where the site power supply begins: supply intake, commercial metering, distribution across feeders and protection against overload and short circuit. Ratings, apparatus and panel layout follow your single-line diagram; in a delivered set the panels ranged from 100 to 1600 A. LK Energy Group is an Odesa-based manufacturer of switchgear equipment; company since 2005, own factory since 2015: we design and build VRPs for your specific task, with a warranty and compliance with current standards. Technical datasheet (PDF) ↓ Questionnaire for calculation → The warranty for VRP is 2 years (extended to 5 years by agreement); enclosure metalwork — 10 years.

FAQ
What is a VRP/UVR and which facilities is it designed for?
What current is the VRP rated for?
The rated current of the assembly (InA) is set by the main device and the enclosure around it — the type has no fixed ceiling. In delivered work: a set from 100 to 1600 A in one construction (VRP-9 at 1600 A, passport serial no. 173910). The rating for your load is defined by the project design.
Is it a standard design or built to project specification?
Can incoming supply, metering and distribution be combined in a single VRP?
What standards does LK Energy equipment comply with?
