FAQs
SP6485D is designed to pair directly with SRD threaded cap receptacles, enabling a secure, interlocked connection. The three-wire, four-pole configuration plus Style 2 grounding ensures reliable fault isolation and proper grounding. For field deployment, ensure cable diameter within 0.875-1.375 in and verify 480 Vac supply compatibility, then tighten the grip and seal to maintain enclosure integrity.
Key specs include a 60A amperage rating, 480 Vac voltage rating, 60-400 Hz frequency range, and a three-wire, four-pole configuration. The device uses copper-free aluminum housing with brass contacts and features a Style 2 grounding method. Cable diameter range is 0.875-1.375 inches, and it’s intended for use with SRD interlock receptacles in hazardous locations.
Yes. SP6485D carries NEC/CEC compliance and NEC hazardous ratings, including Class I Division 1 and 2, Class II Division 2, and Class III, with NEMA ratings 7, 12, 3, and 9. This combination supports safe operation in hazardous/classified locations and aligns with global industry standards for explosive environments.
SP6485D is designed to meet NEC/CEC standards and is associated with UL certification for hazardous locations. Its NEMA ratings (7, 12, 3, 9) and area classifications—Hazardous/Classified Locations—provide essential regulatory assurance for equipment intended for demanding industrial environments, including oil, gas, and chemical processing facilities.
The copper-free aluminum housing reduces weight and corrosion risk, which lowers maintenance overhead. The integrated cable grip and neoprene bushing improve seal integrity and vibration resistance, reducing downtime. UL/NEC/CEC certifications support compliant installations, helping to minimize regulatory-related delays and boosting overall system uptime in harsh environments.
