Dimensions

The size matching the type and range of devices and individual needs of the Client.

Typical dimensions:

  • Height: 1100/1900/2100/2200 mm;
  • Width: 400/600/800/820/850/1000/1050/1250/1400 mm;
  • Depth: 250/300/400/600/620/800 mm.

Equipment

The devices are installed as required by the Client.

  • Vertical installation profiles: fixed permanently to the walls of the enclosure, ready for installation bases or current circuit post insulators;
  • Installation base: galvanised, installed on vertical installation profiles made of galvanised sheet for current circuit switches;
  • Wire ducts with the cross section matching the type and number of cables;
  • Masking panels: made of plastic or sheet metal, installed to the enclosure structure or to the internal frame with masking panel clamps;
  • The control panel with the mimic panel, made in a unique way by applying offset-printed sheets on the whole surface of the panel, with the possibility of printing any design. Installed in the internal frame;
  • Lighting and heating, with heating circuits, and a thermostat with the heating element in the lower part of the cabinet. Lighting: two fluorescent lamps installed in the upper part to ensure uniform illumination along the entire width. Limit switches and a cam switch are installed in the cabinet (the components may be installed in any place, as required by the Client);
  • Cable clamps with the cable management bar;
  • Galvanised steel earthing rail;
  • Ventilation with a fan and proper openings in the enclosure to allow continuous flow of air;
  • Document holder.

The enclosure can additionally host circuits of the primary electrical installation developed by the designer for the specific project.

Accessories

  • Plinth – solid, welded;
  • FB concrete or FM aluminium base – matching the dimensions of the cabinet;
  • GO fire bulkhead – preventing penetration of fire and other factors inside the cabinet.
