Certifications and compliances

• UL standards: UL1203 (APJ plugs only), UL1682, UL1686
• CSA standard: C22.2 No. 182.1
• CE marked to the Low Voltage Directive (LVD) 2006/95/EEC (20-100A plugs and receptacles only)

• Circuit breaking – plugs through 100 ampere rating may be disconnected under load; 150-400 ampere units are for service disconnect use only
• Keyed sleeve on the receptacles accept only plugs of the same amperage rating, style and number of poles, making it impossible to mismate, and providing for positive polarization
• Split pin contacts are made of high grade naval brass to ensure long life, and provide 360º of contact between the pin and sleeve to reduce heat rise and eliminate arcing
• Any arc formed when the plug is being removed is instantly snuffed in the deep confined insulated arcing chamber
• Grounding contacts that make first and break last in the unlikely event of keyway failure
• Safety barrier between insulator body and metal housing minimizes risk of energizing handle body due to stray conductor strands
• Gasketing system provides NEMA 4 watertight integrity
• Extra wide electrical spacing allows for maximum safety
• All aluminum Uni-Shell construction provides superior strength in abusive environments
• Insulator materials are the result of intensive testing; selection has been made based on highest dielectric strength, maximum mechanical and impact resistance, lowest moisture absorption and highest arc tracking resistance
• A Tri-Lock cable grip has three clamps which provide even gripping and superior cord clamping
• Lockout plug allows users to comply with OSHA lockout/tagout requirements
• Wrenching surfaces make Arktite plugs quick and easy to assemble
• A variety of installations is possible due to the availability of several types of back boxes
• Reversible interiors, 30, 60 and 100 ampere (except 30 and 60 ampere, 5-pole) Arktite plug and receptacle interiors are interchangeable using a screwdriver; this makes it possible to feed a normally de-energized receptacle from an energized plug with usual Arktite safety; no energized contacts are exposed

• Metallic receptacle housings, plug and cord connector bodies – high impact strength copper-free aluminum
• Back boxes – 20, 30, 60, 100, 150 and 200 amperes: cast aluminum; 400 amperes: Feraloy iron alloy
• Insulation – 2-, 3- and 4-pole: fiberglass-reinforced polyester; 5-pole: melamine
• Contacts: pressure, solder, binding screw – brass; crimp/solder 20, 30, 60, 100 amperes – leaded red brass; crimp/solder 150, 200, 400 amperes – telurium copper
