NEC — N1 Series (Non-Factory Sealed):
Class I, Division 1 and 2, Groups C, D
NEMA 3R, 4X, 7CD, 12
Applications
• Listed for use in Class I, Division 1 and 2, Group C and D
atmospheres such as:
— Diethyl ether
— Methyl ethyl keytone
— Acetone
— Toluene
— No. 3 fuel oil
— Ammonium hydroxide (20%)
— Benzene
— Regular unleaded gas
— Ethyl acetate
— Hexane
— Methanol
• Not suitable for:
— Ethylene dichloride
— Partially halogenated hydrocarbons
• Sealing ttings must be eld installed adjacent to enclosure on
all conduit runs.
• Explosionproof, with sealing ttings 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.
• Push buttons and selector switches are used in conjunction
with contactors or magnetic starters for remote control of
motors in hazardous locations. They provide circuit control and/
or selection.
• Pilot lights provide visual assurance that an electrical function is
being performed at a remote or local hazardous location.
Features
• Nonmetallic 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. Nonmetallic enclosures
with corrosion resistant parts coated with epoxy, Teon®
®
Mylar
chemicals.
• Unique labyrinth-path construction assures ame-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 exural strength, and
1,200,000 psi exural 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 ultraviolet light and water.
• Excellent conduit connection strength.
• Excellent resistance to attack by fungi and mold.
• Superior ammability resistance.
