Short Description

EDS Series factory sealed tumbler switches prevent ignition of hazardous atmospheres by containing any arcing within a factory sealed enclosure. Many models are suitable for use in locations where Group B gases (hydrogen) are present. Front operated and side rocker arm models are available, and both types can be padlocked in either the on or off position.

Features

  • Corrosion resistant, strong stainless steel hex head cap screws attach cover/body/sealing chamber assembly for approved flame-tight construction
  • Enclosures have external mounting lugs for ease of mounting
  • Smooth, rounded integral bushing in each hub protects conductor insulation
  • Enclosures furnished with internal ground screw
  • Factory sealed switches are designed to a UL Standard so that any arcing devices are contained within an explosionproof labyrinth switch (standard switch and sealing chamber on select models)
  • Tumbler switch devices are approved for installation without additional external sealing fittings
  • 20 Amp 4-way and all 30 Amp models utilize a switch enclosed in separate sealing chamber
