Explosion-proof equipment plant
PKIE-PKL explosion-proof rocker switches are intended for application in hazardous areas. Explosion-proof rocker switches are the most familiar to the main part of users. Easy principle of operation of the rocker switch enables to assemble convenient and reliable diagrams of lighting control. Large operating surface of the key allows using the switch in protective gloves. The key of the switch is equipped with a canopy for protection against accidental pressing.
Scope of application – outdoor and indoor hazardous areas, mines non-hazardous with gas or dust as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) regulating application of electrical equipment in hazardous and non-hazardous areas at dangerous production facilities of danger class I, II, III, IV supervised by Rostechnadzor and national technical supervision bodies of the CIS countries.
