Eaton Crouse-Hinds SP3463D plug - Hazardous/Classified Locations

30A at 480 VAC meets peak-load demands of modern industrial equipment, delivering reliable current with margin for startup surges. This results in fewer nuisance trips and lower maintenance costs across critical lines in hazardous areas where downtime directly impacts production. Applications span conveyors, pumps, and motors in chemical plants, refineries, and mining sites, where dependable power and robust protection are essential for safe, continuous operation. Three-wire, four-pole configuration with Style 2 grounding provides a robust fault path and clear current return, improving overall electrical safety in challenging environments. This design supports regulatory compliance by maintaining consistent fault protection during maintenance in hard-to-reach spaces and under harsh conditions. It is an ideal fit for SRD interlock systems requiring precise door-actuated control and reliable coordination with other explosion-protected components in hazardous locations. Copper-free aluminum housing delivers corrosion resistance and lighter weight compared with traditional copper-containing enclosures, extending service life in aggressive environments. The business impact is lower maintenance costs and less frequent replacement, even in salt spray, dust, or chemical exposure. Applications include chemical processing plants, offshore platforms, and outdoor installations where environmental exposures are chronic, ensuring predictable performance year-round. Copper-brass contacts provide durable, high-quality conductivity across a wide frequency range (60-400 Hz), maintaining consistent performance under vibration and temperature swings. This reduces contact wear and replacement costs while supporting reliable operation of high-demand equipment. Beneficial in continuous-operation machinery found in oil and gas processing, mining, and heavy manufacturing environments. Integrated cable grip and neoprene bushing deliver improved seal, strain relief, and ingress protection, minimizing moisture ingress and cable movement. This reduces seal failures and simplifies installation or servicing in confined spaces or remote locations, accelerating maintenance windows. The combination supports long-term reliability for outdoor, damp, and dusty environments where cables are routinely stressed. NEC/CEC compliance with area classifications for Hazardous/Classified Locations and NEMA ratings 3, 9, 12, and 7 underpins broad regulatory adherence and standardization. The SP3463D’s compatibility with SRD interlock ecosystems enables a unified interlock strategy across multiple industries—oil and gas, chemical processing, mining—while streamlining procurement, inventory, and training for maintenance teams, technicians, and engineers.
