LV distribution boards

The low-voltage distribution devices produced by Extreme LTD perform the functions of receiving, accounting and distributing electrical energy of three-phase alternating current with a voltage of 380/220V in networks with a blindly grounded neutral, as well as protecting lines from overloads, short-circuit currents and leakage currents.

Switchboards and cabinets are designed to accommodate various electrical devices that distribute electricity inside buildings. Their main purpose is to help control, measure, protect and regulate electricity, and ensure the operation of related systems.

Switchboards produced by Extreme LTD can include:
  • 0.4 kV cabinets;
  • input, computing and input-computing cabinets;
  • cable cabinets;
  • input cabinets with automatic transfer switch;
  • distribution cabinets;
  • distribution and accounting cabinets;
  • cabinets for automatic backup switching;
  • electric motor control units;
  • capacitor units;
  • cabinets for automated processing and data transmission.
