Explosion-proof connectors for outdoor installation VS MK, are connectors for connecting mobile equipment and
designed for rated voltage no more than 690 V DC and alternating current with a frequency of 50 (60) Hz and rated current no more than 125 A.
Explosion-proof connectors by their design can be used both in open production areas and in production facilities engaged in the extraction, processing and transportation of oil and gas, the chemical industry, as well as in mines and mines hazardous for gas and dust.
