FAQs
Installation should verify correct three-wire, four-pole configuration and proper alignment within the panel with the interior rotated 22-1/2 degrees for optimal mating. Ensure cord diameter falls within 0.55 to 0.70 inches and that the receptacle and plug are compatible within the NPJ family. Use approved tools and follow standard safety practices to minimize downtime.
Yes. The NPJ3483 S4 is designed for compatibility within the Arktite NPJ plug family, supporting typical 30A, 3-wire 4-pole configurations. It accommodates standard cord diameters in its range and pairs with NPJ receptacles that share the same series and grounding style, simplifying procurement and field terminations.
Best suited for ordinary/non-hazardous locations with demanding duty cycles, such as manufacturing lines, pumps, and conveyance systems. The Krydon body resists chemical exposure and impact, while the 4X enclosure rating protects against moisture and corrosion, ensuring reliable connections in outdoor, washdown, or damp settings.
The NPJ3483 S4 aligns with NEC/CEC standards, carries a NEMA 4X rating, and has UL certification. These certifications ensure safe operation in non-hazardous locations, provide ingress protection against dust and water, and verify compliance with electrical safety and performance requirements critical for regulatory audits and insurance compliance.
Expect reduced maintenance downtime due to rugged Krydon construction, longer service life in harsh environments, and fewer field terminations due to reliable mating and standardization within NPJ-series plugs. The 600 Vac/250 Vdc rating and 50–400 Hz compatibility also reduce adapter needs, lowering lifecycle costs and simplifying spare parts inventories.
