Eaton SP6463D Plug - 60A, 480 Vac for Hazardous Locations
Part Number: SP6463D
Quick Summary
Eaton SP6463D plug delivers rugged interlock-ready connectivity for explosion-protected installations in industrial facilities. Maintenance teams often wrestle with secure cable routing and safe operation in hazardous zones, where a poorly designed connector can trigger costly downtime. The design supports NEC/CEC compliance, area classifications for Hazardous/Classified Locations, and broad NEMA ratings to meet diverse industrial codes. These features translate to reduced installation time and lower lifecycle costs, while supporting SRD interlock compatibility and easy integration into control panels. For SRD interlock applications, SP6463D provides reliable, code-compliant power interlocks that streamline panel wiring and maintenance.

Eaton Specification Sheet - SP6463D
Feature: 60A, 480 Vac rating with three-wire, four-pole configuration. Benefit: Enables handling of demanding loads with a secure interlock path, reducing startup surges and wear on upstream breakers. Application: Suitable for heavy-duty industrial machinery and motor control panels in hazardous environments. Feature: Copper-free aluminum housing with brass contacts. Benefit: Lighter weight and enhanced corrosion resistance without sacrificing conductivity, lowering total cost of ownership in aggressive environments. Application: Outdoor or damp locations and chemical-adjacent facilities. Feature: Grounding style Style 2 and cable diameter range 0.500-0.875 in. Benefit: Ensures proper grounding and reliable strain relief, minimizing torque-induced wear and signaling faults. Application: Field installations with variable cable runs and tight panel clearances. Feature: With cable grip and neoprene bushing. Benefit: Superior seal, easier installation, and reduced ingress of dust or moisture, speeding commissioning. Application: SRD interlock receptacle installations in explosion-protected panels. Feature: Frequency rating 60-400 Hz and material/contacts specs (copper-free aluminum housing, brass contacts). Benefit: Broad compatibility across motor drives and controls while maintaining robust interlock performance. Application: Industrial environments with diversified power profiles and frequent frequency changes.

FAQs
The SP6463D is designed for SRD spring door receptacles and fits standard 0.500-0.875 in cable diameters. Install by securing the cable with the integrated grip, fit the neoprene bushing for sealing, and ensure the Style 2 grounding path is connected to the enclosure. Verify NEC/CEC classifications and torque specs per installation sheets to maintain hazardous-location compliance.
Key specs include 60 A amperage rating, 480 Vac voltage rating, 60-400 Hz frequency range, and a three-wire, four-pole configuration with brass contact material and copper-free aluminum housing.
Yes. The plug is designed for Hazardous/Classified Locations with NEC/CEC compliance and supports multiple NEC hazardous ratings (Class I, II, III across divisions) as part of its certified construction.
The copper-free aluminum housing reduces weight and corrosion risk, while brass contacts provide reliable conductivity. The cable grip and neoprene bushing simplify installation and seal integrity, leading to fewer field reworks and lower maintenance costs over time.
