NEC — N1 Series (Non-Factory Sealed): Class I, Division 1 and 2, Groups C, D NEMA 3R, 4X, 7CD, 12

Intraground™ N1 Series Control StationsNonmetallic10 Amp, 600 Vac Max. for Heavy Duty Use.

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 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.

• 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, Teflon® or Mylar® , these control stations offer unsurpassed resistance to 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 ultraviolet light and water. • Excellent conduit connection strength. • Excellent resistance to attack by fungi and mold.• Superior flammability resistance.

Related Products• Sealing fitting must be installed at each conduit entrance

of the N1 enclosure to be explosionproof. See Hazardous Location Fittings Section.

Intraground™ N2 Series Control StationsNonmetallic10 Ampere, 600 Vac Max. for Heavy Duty Use.

Applications• Listed for use in Class I, Division 2, Group B, 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.

• Listed for use in Class II, Division 1 and 2, Groups E, F and G.• Dust-tight construction. After 32 hour UL test, no magnesium

dust entered the enclosure.• 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• Factory sealed — no external seals required.• 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, Teflon® or Mylar® , these control stations offer unsurpassed resistance to chemicals.

• Silicone gasket, specially designed for the labryinth-path point between cover and body, prevents entrance of moisture and dust.

• Molded of high-tensile 30% glass reinforced thermoplastic polyethermide. Enclosure walls are 5/16” thick.

• Typical mechanical properties of 17,000 psi tensile strength, 3% elongation at break, 27,000 psi flexural strength, and 1,100,000 psi flexural modulus (UL tests showed 18,918 psi tensile strength and 30,675 psi flexural strength).

• Electrical properties of sample specimens: dielectric strength of 490 at 1/8” and a comparative track index of 185V/0.058”.

• Superior impact resistance. • Extremely low water absorption. This important quality assures

dimensional stability.• Excellent resistance to ultraviolet light and water. • UL Temperature Index (continuous use temperature): +130 °C

(+266 °F) electrical properties, +130 °C (+266 °F) mechanical properties with impact, and +140 °C (+284 °F) mechanical properties without impact.

• Superior flammability resistance. • Excellent pull-out resistance.
