Explosion-proof terminal boxes of KKVA (S) series

PURPOSE AND SCOPE OF APPLICATION

Explosion-proof terminal boxes of KKVA series are manufactured with the number of holes from 1 to 4. The material allows application of the boxes in aggressive atmospheres, including marine conditions.

KKVA boxes with 90 mm diameter may be supplied completed with terminal clamps for wires with cross-section up to 4 mm2, boxes with 144 mm diameter may be supplied completed with terminal clamps for wires with cross-section up to 35 mm2 which may be numbered and formed in blocks. Explosion-proof terminal boxes of KKVA series allow installation on the walls and ceiling at right angle.

The boxes are completed with: inner and outer stainless steel ground clamps, stainless steel clamp screw for fastening of the box cover, sealing ring for ensuring IP66/67, outer anti-torsion clamp.

Full production cycle from foundry patterns to finished products is carried out by "ZAVOD GORELTEX" Co. Ltd. in the territory of the Russian Federation.

Scope of application – outdoor and indoor hazardous areas, as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1999), Ch. 7.3 of Electrical Installations Code, Ch. 7.4. of Electrical Installations Code, other codes regulating application of electrical equipment in hazardous and non-hazardous areas at dangerous production facilities of I, II, III, IV hazard class supervised by Rostechnadzor and national technical supervision bodies of the CIS countries.
