Class II, Division 1 and 2, Groups E, F, G
Class III
NEMA 3, 7 BCD, 9EFG

Applications

• Designed to prevent arcing of enclosed switches in ignitable
atmospheres during connect and disconnect operation of
lighting and light power loads.

• For use in classied areas where ignitable vapors, gases or

highly combustible dusts are present.

• For installation in:

— Chemical plants
— Petrochemical plants

— Reneries

— Other process industries

Features

• Enclosures have external mounting lugs for ease of mounting.

• Smooth, rounded integral bushing in each hub protects
conductor insulation.

• Enclosures furnished with internal ground screw.

• 20 Amp and 30 Amp units available for use with 120-277 Vac.

• Factory sealed switches are designed to a UL Standard so
that any arcing devices are contained within an explosionproof
labyrinth switch (standard switch and sealing chamber on
select models). Tumbler switch devices are approved for

installation without additional external sealing ttings.

• 1/2” and 3/4” 1-gang units suitable for Class I, Group B, in
addition to Class I, Groups C and D; Class II, Groups E, F and
G; and Class III.

• 20 Amp 4-way and all 30 Amp models utilize a switch enclosed
in separate sealing chamber. Smooth double-face, accurately

ground surfaces on sealing chamber ange mate with cover
and body to provide positive ame-tight construction.

• Sealing chamber has prewired factory sealed pigtail leads to
switch.

• Corrosion resistant, strong stainless steel hex head cap screws
attach cover/body/sealing chamber assembly for approved

ame-tight construction.

• Threaded stainless steel operating handle provides positive
Corrosion resistant operation.

• Choice of front-operating or side rocker arm handle—each may
be locked in ON or OFF position.

Standard Materials

• Body and cover: malleable iron

• Sealing chamber (on select models): copperfree (4/10 of 1%
max.) aluminum

• Handle: nylon 6/6

• Optional nameplate mounting bracket: corrosion resistant
stainless steel

Standard Finishes

• Tumbler switches: triple-coat—(1) zinc electroplate,
(2) chromate, and (3) epoxy powder coat

to control stations with existing cover bolts.

— Pre-drilled holes in middle of bracket allow mounting of

customer’s circuit identication nameplate; epoxy glue may

also be used for mounting (phenolic nameplate not included).

— Bracket eliminates costly eld installation of drilling and

tapping to accommodate circuit identication nameplate.

— Brackets t side-by-side on 2-, 3- and 4-gang boxes and

3-devices.

• UL Standards: UL 894, UL 1203

• UL Listed: E10523, E81751

• cUL Listed: E81751, E810523

Ordering Information for ”Custom” Units

• Devices, covers and bodies may be ordered separately so that

a different EDS chamber/switch assembly may be used in each
gang.

• Order components separately as follows:
(1) select mounting body catalog number,
(2) select cover catalog number with desired switch operation

(1-pole, 2-pole, 3-way or 4-way).

How to Order Hub Arrangements

• Simply send sketch indicating sizes and locations for brazed

hubs on body or bodies selected from catalog listings. Orient
sketch so that cover opening faces front and mounting lugs
face upward and downward (box wall opposite cover should be
referred to as the back of box).

Bodies and Hubs Available

• Tumbler switches may be ordered in single thru ve gang deep

malleable iron blank bodies with brazed hubs as specied at

any location.

• Tumbler switches may be ordered with tandem malleable iron

boxes with additional brazed hubs as specied.

• Standard malleable iron single and 2-gang tumbler switches

may be ordered with additional brazed hubs as specied.

• Single and 2-gang tumbler switches may be ordered with

aluminum boxes with additional brazed hubs as specied.

Cast Device Box Ordering Information

Determine catalog number as follows:

(1) Select EFD device box catalog number;
(2) Select ”Standard Hub Arrangement

Diagram” number; and

(3) Select symbols that represent hub

sizes from ”Symbol Table.” (Use ”0”
where no hub is required, and separate
the various divisions of the complete
catalog number by dashes.)

Example

The blank body device box selected is
EFD3NL and the hub arrangement is
diagram #8. Hub ”a” is to be 3/4” brazed
threaded; hub ”b”, 1” brazed threaded;
hub ”c”, 3/4” brazed threaded; hub ”d”,
no hub is required; and hub ”e”, 1” brazed
union.
The complete catalog number will be:

EFD–3NL–8–23203E

Standard Hub Arrangement Diagrams

Hub ”a” is always TOP of box

2-, 3-, 4- and 5-Gang (Front View)

If a ”Standard Hub Arrangement” is not
suitable for the application, or when hubs
are to be more accurately spaced, submit
sketch locating hubs (1) from centerlines
of walls and (2) from outside back of box
(or from mounting lug surface if lugs are
supplied).

All hubs will be located in centerlines of
walls and evenly spaced unless
otherwise specified.
