Roof and bottom

  • Gabled roof with a ventilation maze and ventilation to prevent the accumulation of water and moisture.


  • Has an opening that allows the introduction, through an additional fire bulkhead, of cables from the cable duct;
  • Prepared for the fire bulkhead, using bolted connections.


Dimensions adapted to the type, amount of equipment and individual needs of the customer.Typical implementations:

  • 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 is selected each time according to the needs of the customer.

  • vertical mounting profiles – permanently attached to the walls of the enclosure suitable for mounting plates or current path support insulators;
  • mounting plate – galvanized, mounted on vertical mounting profiles made of galvanized sheet metal under the current track insulators;
  • comb trays – with a cross-section adapted to the type and amount of cabling;
  • Masking plates – made of plastic plates or metal sheets, mounted to the housing structure or internal frame, with the help of mask plate brackets;
  • control panel with synoptic board – made in a unique way, by applying offset printed adhesive sheets to the entire surface of the board, with the possibility of printing any graphics. Mounted in an internal frame;
  • lighting and heating – heating circuits, thermostat along with heating resistor; located in the lower part of the cabinet. Lighting – two fluorescent lamps, assembled in the upper part, so that we get an even intensity of lighting across the width. Limit switches and a panel switch are mounted in the cabinet
  • (It is possible to install the apparatus anywhere according to the customer’s requirements);
  • Cable holders with mounting bar;
  • galvanized steel grounding rail;
  • ventilation – allowing constant airflow through the use of a fan and proper opening of the housing;
  • document pocket.

The enclosure can additionally contain the circuits of the basic electrical system each time prepared by the designer, depending on the specific project.


plinth– full, welded;
FB concrete or FM metal foundation – fitted to the dimensions of the cabinet;
fire bulkhead GO – prevents fire and other agents from entering the interior of the cabinet.
