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 classified areas where 

ignitable vapors, gases or highly 

combustible dusts are present. 

• For installation in chemical and 

petrochemical plants, refineries, and 

other process industries. 

Features: 

All Tumbler Switches 

• EDS and EFS 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-ampere and 30-ampere units 

available for use with 120-277 Volt A.C. 

Features: 

EDS Factory Sealed Tumbler Switches 

• Factory sealed switches are 

designed to a UL Standard so that 

any arcing devices are contained 

within an explosionproof lybryinth 

switch (standard switch and sealing 

chamber on select models). EDS 

tumbler switch devices are approved 

for installation without additional 

external sealing fittings. 

• 1/2” and 3/4” single 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. 

• 20Amp 4-way and all 30Amp models 

utilize a switch enclosed in separate 

sealing chamber. Smooth double-face, 

accurately ground surfaces on sealing 

chamber flange mate with cover and 

body to provide positive flame-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 flame-tight construction. 

• Threaded stainless steel operating 

handle provides positive corrosionresistant 

operation. 

• Choice of Front-Operating or Side 

Rocker Arm Handle—each may be 

locked in ON or OFF position.

Applications 

• Listed for use in Class I, Group C 

and D, Division 1 and 2 atmospheres 

such as diethyl ether, methyl ethyl 

keytone, acetone, toluene, No. 3 fuel 

oil, ammonium hydroxide (20%), 

benzene, regular unleaded gas, ethyl 

acetate, hexane and methanol. Not 

suitable for ethylene dichloride and 

partially halogenated hydrocarbons. 

Sealing fittings must be field installed 

adjacent to enclosure on all conduit 

runs.† 

• Explosionproof. With sealing fittings 

installed at each conduit entrance, 

the N1 Series enclosures withstood 

a hydrostatic test of four times the 

maximum internal explosion pressure 

that could be developed from a gas or 

vapor explosion in actual use. 

Features 

• First UL listed non-metallic tumbler 

switches available for Class I, Div. 1 

locations. 

• Non-metallic construction with metal 

imbedded grounding grid. No need 

to install special wires and parts for 

grounding. Feed-thru or dead end 

grounded 1/2” or 3/4” conduit openings 

for threaded conduit. 

• Special grounding wire furnished 

with each box provides safe grounding 

when cover is removed. 

• Ideal for use in corrosive environments. 

Non-metallic enclosures 

with corrosion resistant parts coated 

with epoxy, Teflon ® or Mylar ® , these 

switches offer unsurpassed resistance 

to a wide variety of corrosive 

chemicals. 

• Unique labyrinth-path construction 

assures flame-tight joint between body 

and cover. 

• Silicone gasket, specially designed 

for the labyrinth-path joint, prevents 

entrance of moisture without interfering 

with the venting of cooled hazardous 

gases and vapors. 

• Typical mechanical properties of 

24,500 psi tensile strength, 3% elongation 

at break, 33,000 psi flexural 

strength, and 1,200,000 psi flexural 

modulus.

• Electrical properties of sample 

specimens: dielectric strength (in air) 

of 769 at 1/16”. 

• High strength thermoplastic polyetherimide, 

together with thick walls 

(5/16”) and sound structural design 

(rounded corners) provides superior 

resistance to impact and crushing. 

• Excellent resistance to ulraviolet 

light and water. After 336 hours of 

immersion in water at 82ûC and 720 

hours of exposure to ultraviolet radiation, 

there was no appreciable change 

in tensile strength. 

• Excellent conduit connection strength. 

UL pull-out and bending resistance 

tests resulted in no effect on conduit 

connections. 

• Excellent resistance to attack by 

fungi and mold. 

• Excellent Heat Deflection Temperature. 

At 264 psi, in accordance 

with ASTM D648 testing procedure, 

sample specimens rated at 410°F 

(the temperature required to deflect 

the material .01”).

• UL Temperature Index (continuous 

use temperature): 338°F electrical 

properties, 338°F mechanical properties 

with impact. 

• Superior flammability resistance. 

After five UL gas burner tests, where 

flame was applied directly to the box, 

there was no dripping of burning parts 

and enclosure retained its integrity.
