The boxes are designed for making connections (branching) of electrical cable networks with voltage up to 250 V, and with a decrease in the number of terminals - up to 320 V DC and 380 V AC, as well as fiber-optic cable lines with optical radiation.
They can be used in all industrial areas, including:
- Fuel industry;
- Oil and gas processing, petrochemical and chemical industries;
- Mining and processing industry (according to explosion protection marking); Ferrous and non-ferrous metallurgy;
- Pulp and paper and food industry;
- Energy, incl. nuclear power;
- Defense industry;
- Mechanical engineering;
- Transport, including sea and river;
- Water supply, sewerage and waste disposal, or treatment facilities.
Intrinsically safe boxes are made in the form of a rectangular case with a hinged cover made of sheet steel. The cover is equipped with a turnkey double-bit lock with the option of installing a sealing eyelet (on request).
Terminal clamps or a panel of optical adapters with a splice cassette are installed inside the housing on the mounting panel. On the side walls of the casing there are cable glands in accordance with the order. At the corners of the case, there are fasteners that allow you to fix the boxes on almost any surface.
The box body provides the degree of protection against external influences in accordance with GOST 14254 not less than IP65. Grounding studs are located inside and outside the housing, which in turn can be connected to a mounting plate or rail for terminal blocks.
To buy the IRSK Device, you need to contact the managers.
