OU-S

Application

  • A universal solution designed for indoor installation;
  • To power (GPZ stations), industrial and construction facilities;
  • For apparatus up to 4000A;
  • To provide a high degree of protection for switchgear, control, control and automation equipment;
  • For series connection in sets.

Design description

Enclosure

  • Indoor, free-standing or wall-mounted on a pedestal;
  • Skeletal, made of a steel frame sheathed in steel or aluminum sheets (joining by welding and bolted connections);
  • Powder coating in any color (RAL) and surface texture with high resistance to deterioration;
  • combined with a plinth;
  • polyurethane foam seals.

Frame – steel frame

  • Made of steel profiles joined by welding;
  • Has a hole for attaching a mounting plate or vertical mounting profiles.

Side covers

  • Mounted to the frame with allen key screw connections;
  • The thickness of the sheet metal adapted to the dimensions;
  • When the side covers are installed, the width dimension of the housing does not change.

Basis

  • 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.

Doors

  • Solid or transparent;
  • Single-sided or double-sided (back cover), for better access to the apparatus;
  • Single-leaf or double-leaf;
  • Locked with a cylinder lock (any shape) or a basquil lock locked with a system cylinder and an additional padlock;
  • Three-point locking;
  • Internal hinges;
  • Opening angle 120 deg;
  • Grounding studs with wiring.

Roof and bottom

  • Made of a height-adjustable cover for additional ventilation;
  • The cover has an additional hole with grommets, allowing the introduction of wiring from cable routes;
  • Transport handles.

Dimensions

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

  • height: 1800/2000/2200 mm;
  • width: 400/600/800/850/1000/1050/1250/1400 mm;
  • depth: 250/300/400/600/800 mm.

Equipment

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

  • Vertical mounting profiles – steel hole-mounted to the frame;
  • 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;
  • Internal frame tilting 19” – symmetrical or asymmetrical;
  • Cable holders with mounting bar;
  • 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 – two fluorescent lamps, assembled in the upper part, thanks to which we get an even intensity of lighting across the width. In the cabinet are mounted limit switches and a panel switch (it is possible to mount the apparatus anywhere, according to customer requirements);
  • Ventilation – allowing constant airflow through the use of a fan and proper opening of the housing.

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

Accessories

plinth – welded, made in solid or ventilated version with any height.
