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:
ɀ to prevent arcing of enclosed device from
causing ignition of a specific hazardous
atmosphere or atmospheres external to the
enclosure
ɀ 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
ɀ in non-hazardous areas where sturdy,
durable enclosures are required
ɀ in conjunction with magnetic starters or
contactors for remote control of motors
Manual motor starting switch enclosures are
used:
ɀ for manual starting of small ac or dc motors
ɀ 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:
ɀ reduce installation problems
ɀ eliminate external seals
ɀ lower installation costs
ɀ improve safety
ɀ are used with general purpose snap and
pushbutton type switches
ɀ standard neoprene covers for front
operated pushbuttons. Prevents
accumulation of dirt and entrance of water
around operating shafts
ɀ mounting lugs and taper tapped hubs with
integral bushings
ɀ large machine screws for fastening covers
to bodies
ɀ lockout provisions on front operated push
button (marked ‘‘STOP’’ and ‘‘OFF’’) and
selector switch covers
ɀ lockout hole for padlock having 1⁄4⍯ hasp is
provided when used with covers for front
lever and side rocker type operation
ɀ close tolerances in machining of wide,
mating flanges and journalled shafts and
bearings for front button operation, produces
flametightness of enclosure joints
ɀ on enclosures with front lever and side
rocker type operating handles, threaded type
shafts and bushings are used to ensure
flametightness
ɀ dead end (EFS or EDS) or through feed
(EFSC or EDSC) hubs – 1⁄2⍯ to 1⍯ sizes
ɀ Shafts – stainless steel
ɀ Shaft bushings – stainless steel
ɀ Rocker handle and pushbutton guards –
