The EFD/EFDB and EDS series offer a wide choice of push button, selector switch and pilot light control stations for use in hazardous locations. These factory sealed control stations are designed to confine any arcing within the enclosure to prevent ignition of the surrounding atmosphere. Many models are suitable for group B (hydrogen) when external seals are installed at each conduit entrance. Featuring a small footprint and Appleton durability, these models have long been the preferred choice for safe, reliable control of industrial motors and equipment.
