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

*See suffix GB in Options section.

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.

Options:

The following special options are available from the factory by

adding suffix to Cat. #:

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.
