Control Stations & Pilot Lights

Appleton ATX EFD/EFDB & EDS

Appleton ATX explosion proof, dust-ignition proof EFD/EFDB and EDS Series factory sealed control stations confine the arcing of devices within the enclosure, preventing ignition of ignitable atmospheres during control operation of motors and other equipment in hazardous area locations.

A variety of ATEX push buttons and selector switches are available for use in conjunction with contactors or magnetic starters for remote control of motors – the ATEX switches provide circuit control and/or selection.

Pilot lights are explosion proof lighting available to provide visual assurance that an electrical function is being performed at a remote or local location. EFD/EFDB and EDS Series control stations are designed for use in classified areas where flammable vapors, gases or highly combustible dusts are present in hazardous area locations.

Control Stations

Features

Explosion-proof and Dust-Ignition proof control stations. Ideal for installation in chemical and petrochemical plants, refineries and other hazardous area process industries.
Factory sealed, eliminates the need for adding sealing fittings to the control station and compound at each conduit entrance. The ATEX certified devices are enclosed in separate sealing chamber that has smooth, double flanges that mate both to the cover and mounting enclosure.
EFD/EFDB factory sealed pilot lights are supplied with red jewel/guard assembly and 120 Vac/Vdc, 50/60 Hz, 6 Watt, Type 6S6 lamp.
EFD/EFDB factory sealed selector switches furnished with nylon cam-operated, heavy-duty push buttons for either 2-position or 3-position maintained contact operation. They offer high thermal and arc resistance, high dielectric strength.
EDS factory sealed push buttons are available with dust cap for use in areas where excessive dust, moisture or corrosive conditions are encountered. Enclosed stainless steel helper spring prevents accidental operation of push button in severe vibration areas.
Heavy-duty push buttons, 10 Amp, 600 Vac rated for hazardous area installations.
EFD/EFDB momentary push buttons are supplied with lockout type guards as standard. A hole in the guard will accept locks with up to 1/4″ hasp. Permits locking of push button to prevent unauthorized operation.
EFD/EFDB backbox supplied with internal ground screw. Accurately tapped, tapered hubs for tight, rigid joints and ground continuity. Smooth, rounded integral bushing in each hub protects conductor insulation.
Corrosion resistant captive stainless steel hex head cap screws hold covers to body.
Stainless steel push button shaft operates within stainless steel bushing assuring long, maintenance free operation.
Push button and selector switch contacts are silver cadmium oxide which are “sealed” in lower phenolic chamber isolated from corrosive elements. Assures positive contact and long, trouble-free operation.
Clearly marked terminals with brass screws assure quick, easy wiring. Pigtail leads from push buttons are factory sealed in sealing well.
