Polyester electrical enclosures - 320mm deep

Polyester electrical enclosures 320mm deep (OT3)

Polyester electrical enclosures 320mm deep (OT3)

The OT3 enclosures with a depth of 320mm comply with a range of requirements for electrical switchgears. They are made of thermosetting glass fibre reinforced polyester which has insulating, slow-burning and self-extinguishing properties, and its typical features is high resistance to weather (UV). These enclosures, due to its multifunctional structure, are applied in the power and telecommunication industry, as well as for general industry purposes.

Additionally, the enclosures with a height of 800 mm are designed for installation of busbar systems and terminal equipment. Our offer for those enclosures includes a selection of four types of insulators.

All types of insulators ensure stable installation, and the spacing of busbars meets the requirements of relevant standards. The spacing of insulators in the enclosure enables the instalation of the terminal equipment with the spacing of 185 mm.

The enclosures can have two types of the roof: skew for outdoor enclosures and flat for indoor enclosures.


  • Cable and measuring connectors in professional power engineering
  • Low voltage switchgear
  • Enclosures protecting electronic devices


  • A wide range of working temperature
  • Resistance to weather conditions (UV)
  • Impact resistance IK 10

  • Construction allows to connect the enclosure with the pedestal or the cable base
  • The modular design allows to set enclosures vertically or horizontally
  • The ventilation system minimizes the accumulation of humidity inside the enclosure
  • Depth of enclosure (320mm) allows for the installation of large-size equipment
