Eaton Specification Sheet - SP3483D
The SP3483D SP plug uses a 30A, 480 Vac electrical specification paired with a three-wire, four-pole configuration to deliver reliable power to heavy-duty equipment in hazardous environments. Business impact includes improved equipment uptime and safer interlock circuits, especially when paired with SRD threaded cap receptacles for quick, repeatable installations in mining, chemical processing, and manufacturing lines. The copper-free aluminum housing and brass contacts reduce weight and resist corrosion, lowering long-term maintenance costs while maintaining conductive integrity. With a 0.500–0.875 inch cable diameter range and Style 2 grounding, it supports flexible field wiring and robust strain relief, minimizing field failures during vibration or thermal cycling. The inclusion of a cable grip and neoprene bushing enhances sealing and ingress protection, easing installation and reducing service calls. Compatibility with NEC/CEC standards and NEMA ratings 12, 3, 9, 7 delivers regulatory confidence across global sites, reducing compliance risk and accelerating procurement workflows. Industry-specific context shows that hybrid facilities with mixed voltage and hazardous zones benefit from a single, standardized interlock plug family, lowering training time and accelerating maintenance planning for shutdowns and commissioning.
