Description
The boards are assembled from a modular system of blocks, so expansion does not require rebuilding the existing sections. The busbars with a rated current up to 6300 A are placed at the rear, top or bottom, depending on where the cables or busways enter. Internal separation is made to forms 1–4b. The degree of protection IP30, IP31 or IP54 is chosen according to the room conditions, and the enclosure colour is RAL 7035. The panels are installed against a wall, back to back or standing alone. The panel width is 400–1200 mm, the height 2000 or 2200 mm and the depth 600 or 800 mm. The design can be fixed or fully withdrawable. The scope of supply includes design, final assembly, factory tests, installation and commissioning. The assembly quality is confirmed by participation in the Panelbuilder programme for EMEA panel builders with regular audits. Within the line, DC boards, reactive power compensation units, ATS devices, transformer substations and transformer busbar connections are also made.
How to choose
The current level is set by the main busbars, and outgoing lines up to 630 A are built on the fuse switch disconnector system. Air circuit breakers are taken for incomers and high-power outgoing lines, and plug-in modules for motor starters and compact circuit breakers. For motor starters and power supply there are also withdrawable modules. If the board is in a dusty or damp room, change from IP30 to IP54. Non-standard schemes, for example ATS, are assembled as a special version.
