The explosion-proof plug VR MK VN is a connector for connecting mobile equipment by fully connecting it to the explosion-proof socket VR MK RN or VR MK RV and moving it to the “ON” position and is designed for a rated voltage of no more than 690 V DC and AC with a frequency of 50 (60) Hz and a rated current of no more than 125 A.
Explosion-proof connectors, by their design, can be used both in open production areas and in industrial premises engaged in the extraction, processing and transportation of oil and gas, the chemical industry, as well as in mines and pits hazardous due to gas and dust.
