Product Datasheet

Approvals

Main switchboard (MS) are used in the assembly of the CPS KTP 6 (10 kV) / 0,4 kV (low-voltage component), input devices at industrial sites, in administrative and residential buildings to provide protection from overloads and short-circuits, power metering, and infrequent operational switching of electrical circuits.

MS can have one or two inputs, as well as additional input from the diesel generator. Metal switchboards with single or multiple sections for single-sided or double-sided maintenance are available. Each section can be fitted with protective panels (shields) and doors. Multi-section switchboards are easily assembled and disassembled as required for transportation. Switchboards have cable or busbars inputs. Inputs can be either from above or from below. Output can be both through the sections where the devices are installed and through dedicated sections, which is especially convenient for unilateral maintenance. Power busbars are made of a calibrated copper strip.

  • Input and distribution of power from the CPS
  • Protection against single-phase and multiphase short-circuits, overloads, and leaks
  • Power metering for management and process control purposes
  • Remote control of the main switchboard electrical parameters
  • Busbar sectioning for the safety of maintenance
  • Automatic load switching (ALS section) for boards with two and three inputs on the basis of the microprocessor devices analyzing the system status
  • Operating and emergency status indication of the system
