Applications:
Factory sealed enclosures are installed in a rigid metallic conduit
system for surface mounting adjacent to or remote from equipment
being controlled and are used:
•To prevent arcing of enclosed device from causing ignition of a
specific hazardous atmosphere or atmospheres external to the
enclosure
•In 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 atmosphere may contain hazardous gases and/or dust
•In non-hazardous areas where sturdy, durable enclosures are
required
•In conjunction with magnetic starters or contactors for remote
control of motors
Manual motor starting switch enclosures are used:
•For manual starting of small AC or DC motors
•To provide manual starting and stopping and, in the case of units
with heaters, motor running protection

Features:
Factory sealed devices have many distinct advantages:
•Reduce installation problems
•Eliminate external seals
•Lower installation costs
•Improve safety
•Are used with general purpose snap and pushbutton type switches
•Standard neoprene covers for front operated pushbuttons. Prevents
accumulation of dirt and entrance of water around operating shafts
•Mounting lugs and taper tapped hubs with integral bushings
•Large machine screws for fastening covers to bodies
•Lockout provisions on front operated pushbutton (marked "STOP"
and "OFF") and selector switch covers
•Lockout hole for padlock having 1/4" hasp is provided when used
with covers for front lever and side rocker type operation
•Close tolerances in machining of wide, mating flanges and
journalled shafts and bearings for front button operation, produces
flametightness of enclosure joints
•On enclosures with front lever and side rocker type operating
handles, threaded type shafts and bushings are used to ensure
flametightness
•Dead end (EFS or EDS) or through feed (EFSC or EDSC) hubs – 1/2"
to 1" sizes
•When STOP is indicated, button is automatically red. When START
is indicated, button is automatically green. Otherwise, black
buttons are standard.

Methods of Factory Sealing
EFS/EDS Series
Factory sealed EDS and EFS pilot light, pushbutton and selector
switch control stations do not need external sealing. Device contacts
are factory sealed in explosionproof ESWP contact blocks. Small,
compact enclosures have accurately ground wide flanges on both
the body and cover for a flame-tight joint.
EDS Series
EDS factory sealed snap switches or manual motor starting switches
do not need external sealing. The switches are enclosed in a unique
sealing well with double flanges which mate with the cover and the
body. Small, compact enclosures have accurately ground wide
flanges on body, cover and sealing well for flame-tight joints. Wiring
pigtails are factory sealed from under the sealing well. Reliable
pouring of seals at the factory ensures safe sealing.
