Appleton™ Intraground™ N1 Series non-factory sealed and Intraground™ N2 Series factory sealed control stations are ideal for use in corrosive environments.

These nonmetallic enclosures feature corrosion resistant parts coated with epoxy for unsurpassed resistance to chemicals.

A variety of push buttons and selector switches are available for use in conjunction with contactors or magnetic starters for remote control of motors in hazardous locations.

Pilot lights are available to provide visual assurance that an electrical function is being performed at a remote or local location.
Features
  • 10 Amp, 600 Vac Max. for Heavy Duty Use
  • 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
  • Smooth, rounded integral bushing in each conduit opening protects conduct or insulation. Accurately tapped, tapered conduit openings for tight, rigid joints and ground continuity
  • Stainless steel push button shaft operates within stainless steel bushing, assuring long, maintenance-free operation. Push button and selector switch contacts are silver cadmium oxide which are "sealed" in lower phenolic chamber isolated from corrosive elements
  • N1 Series is designed with unique labyrinth-path construction to assure a flame-tight joint between body and cover. Explosionproof, with sealing fittings field installed adjacent to enclosure on all conduit runs, 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
  • N1 Series has 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"
  • N1 Series is designed with high strength thermoplastic polyetherimide, together with thick walls (5/16") and sound structural design (rounded corners) provides superior resistance to impact and crushing. The N1 Series provides excellent resistance to ult
  • N2 Series is factory sealed, no external seals are required. The dust-tight construction means no magnesium dust enters the enclosure (after 32 hour UL test). It is Listed for use in Class II, Division 1 and 2, Groups E, F and G
  • N2 Series is 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
  • N2 Series provides superior impact resistance, extremely low water absorption (this important quality assures dimensional stability), excellent resistance to ultraviolet light and water, superior flammability resistance and excellent pull-out resistance
