Appleton EFKF34WQ Explosionproof Switch Cover for 3-Way and 4-Way Switches

Appleton EFKF34WQ Explosionproof Switch Cover

Not sure which switch cover fits your 3-way or 4-way setup? The EFKF34WQ is a cover made by Appleton for switches installed in areas where flammable gases, vapors, or dust may be present, like chemical plants and refineries. It is explosionproof and dust-ignitionproof, meaning it contains any internal arcing so it cannot ignite the surrounding atmosphere.

This cover is made for a 3-way or 4-way, non-sealed EFS tumbler switch rated at 120 to 277 VAC, and it is built to fit EFD type single-gang outlet boxes. It is made of malleable iron for long-term durability, and it comes with all the mounting hardware you need, including device mounting screws, an internal ground screw, and stainless steel cap screws. The cover is listed to UL 894/1203 and carries a NEMA 7CD, 9EFG enclosure rating for Class I, Division 1 and 2, Groups C and D; Class II, Division 1 and 2, Groups E, F, and G; and Class III locations.
