FAQs
SP6585 NW is designed to mate with SRD threaded-cap receptacles. Confirm the cable diameter falls within 0.875–1.375 inches, ensure Style 2 grounding is used, and verify the receptacle is rated for the same hazardous-location classification (Class I, Division 1, etc.). Use proper sealing and grip fittings to maintain ingress protection during service.
Plan for a 60A amperage rating, 480 Vac service, and a frequency tolerance of 60–400 Hz. The configuration is four-wire, five-pole with brass contacts and copper-free aluminum housing. This combination supports high-power motors and control circuits in hazardous environments while ensuring reliable contact integrity.
Yes. The SP6585 NW plug is specified for Hazardous/Classified Locations and carries NEC/CEC compliance with NEC hazardous ratings including Class I, Division 1. It is intended for use with explosion-proof SRD interlocks and aligns with typical hazardous-location interconnect requirements.
SP6585 NW aligns with NEC/CEC standards for hazardous locations, provides Class I Division 1 ratings, and offers NEMA compatibility (ratings 12, 9, 7, 3 depending on configuration). UL certification references are available for safety verification, and the component is designed for area classifications associated with hazardous environments.
The copper-free aluminum housing resists corrosion, and the built-in cable grip plus neoprene bushing reduce strain and ingress, lowering maintenance frequency. Brass contacts provide durable electrical performance, while the four-wire, five-pole layout simplifies field troubleshooting and minimizes downtime during routine servicing or interlock inspections.
