Series Factory Sealed push
button stations, selector switches, pilot
lights and tumbler switches are used to
prevent the igniting of external hazardous atmospheres by the enclosed
arcing devices in such areas as:
• Hazardous locations due to the presence of flammable gases or vapors,
combustible dusts or easily ignitable
fibers or flyings
• Installations at petroleum refineries,
chemical and petrochemical plants
and other processing or storage facilities where similar hazards exist
• Use in conjunction with magnetic
starters or contactors for remote control of motors
Features
• Elimination of external sealing
requirements
• Lower installation cost
• NEMA 3 weatherproof
• Color coded wiring-more wiring
space-easier field installation

Factory Sealed devices eliminate the
need for external sealing. The difference is the use of a sealing plate
between the arcing device and the
junction box. The sealing plate confines ignited gases, vapors, flames,
or dust to the arcing device chamber,
preventing them from traveling through
the conduit system. Accurately ground
flanges on both sides of the sealing
plate provide flame-tight joints. Factory
poured seals around the wiring pigtails
insure safe sealing. ( FXCS Series)
