VRSh Power Distribution Cabinet

Purpose

• receiving electrical power from the supply network;
• distribution of power to outgoing outdoor lighting circuits (street lighting, parking areas, courtyard and road lighting networks);
• commercial or technical electricity metering (installation of electricity meters);
• protection of cable lines and connected loads against short circuits and overloads;
• operational power control (manual switching or automated control).

Applications

The VRSh cabinet is used in outdoor lighting systems for:

• streets, roads and highways;
• courtyards, residential complexes and shopping centers;
• industrial facilities, warehouses and parking areas;
• parks and recreational zones.

Mechanical Design

• Configuration: wall-mounted or floor-mounted metal cabinet.
• Enclosure material: steel with polymer powder coating; stainless steel available on request.
• Standard color: grey (RAL 7035) or custom color on request.
• Enclosure protection rating: IP54–IP65 for outdoor installation.
• Climatic category: U1 / UHL1.
• Operating temperature range: −40 °C to +40…+50 °C.
• Door: single- or double-leaf with mounting panel and lock with sealing capability.
• Cable entry: top or bottom via cable glands or entry sleeves.
• Mounting options: pole, foundation frame or building wall.

Typical Functional Configuration

The VRSh cabinet may include:

• main incoming device: switch disconnector, circuit breaker or load break switch;
• electricity metering unit:
  • single-phase or three-phase meter;
  • current transformers (if required);
  • sealed meter compartment;
• distribution circuit breakers for lighting groups;
• protection and switching devices: circuit breakers, RCDs, fuses;
• control and automation circuits: contactors, timers, photo relays, terminal blocks;
• voltage presence and line status indication;
• PE and N busbars with corresponding terminals.

Protection and Safety

• protection of outgoing circuits against short circuits, overloads and leakage currents;
• protective earthing of the cabinet enclosure (PE);
• sealing capability for metering and terminal compartments;
• compliance with applicable electrical safety standards and technical regulations.

Advantages of VRSh Cabinets

• centralized intake, metering and distribution of electrical power for outdoor lighting systems;
• improved reliability of power supply through properly selected protection devices;
• easy operation and maintenance;
• flexible configuration depending on project requirements.
