Features

  • 20 Amp and 30 Amp units available for use with 120-277 Vac
  • UL Temperature Index (continuous use temperature): +170 °C (+338 °F) electrical properties, +170 °C (+338 °F) mechanical properties with impact
  • Excellent heat deflection temperature: sample specimens rated at +210 °C (+410 °F)
  • 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#8221; or 3/4#8221; conduit openings for threaded conduit. Special grounding wire furnished with each box.
  • 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
  • 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
  • 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#8221;
  • Designed with high strength thermoplastic polyetherimide, together with thick walls (5/16#8221;) and sound structural design (rounded corners) provides superior resistance to impact and crushing and excellent resistance to ultraviolet light
  • Operating handle has close-tolerance threaded stainless steel shaft to meet explosionproof requirements. Provides positive corrosion resistant operation. Handle may be locked in ON or OFF position
  • Enclosures have external mounting lugs for ease of mounting
