Crouse-Hinds series EDS and EFS explosionproof pushbutton, pilot light and selector switch control stations are used in conjunction with magnetic starters or contactors for remote control of motors. Pilot lights are used to visually indicate that the desired function is being performed.
EDS and EFS control stations are factory sealed to prevent arcing of the enclosed device from causing ignition of a hazardous atmosphere external to the enclosure. Factory sealing eliminates the need for external seals, simplifying installation and reducing costs.
Typical applications for EDS and EFS control stations include industrial areas, such as chemical plants, oil and gas refineries, paint and varnish manufacturing plants, gasoline bulk loading terminals, grain elevators, grain processing industries, coal processing or handling areas, or metal handling or finishing areas where the atmospheres may contain hazardous gases and/or dusts.
