Hazardous Location Controls
KILLARK hazardous location controls are for processing or storage facilities where flammable gases or vapors, combustible dusts or easily ignitable fibers or flyings are present.
Explosion-proof control devices are available in single or double pushbutton, maintained pushbutton, keyed and non-keyed selector switch, single and double pilot light and pilot light/pushbutton styles. Available factory-sealed control device cover assemblies feature a sealing plate between the arcing device and junction box that eliminates the need for external sealing. Additional features include color coded wiring, stainless steel captive screws for cover assembly, cast conduit hubs in either dead end or feed-through styles and single or two-gang assemblies. Available unsealed control device cover assemblies feature cast copper-free aluminum alloy bodies and covers, open space between gangs for easy wiring from one cover to another, and an internal ground screw. A ground flange joint between the bolted cover and box provide the required flame path. Available accessories include blank covers, replacement keys, replacement LED lamps, sealing fittings, sealing compound and packing fiber, as well as legend plates.
