FAQs
The E1049-81 supports hexagon crimp or solder terminations for 313 kcmil copper conductors. Use the appropriate crimp tool for a secure connection or an approved soldering method per IF 1777 installation sheets. Ensure the copper conductors are prepared to the correct length and seats fully in the contact cavity to prevent hot spots or arcing. The rubber housing provides environmental sealing, and follow the recommended torque and seating guidelines during termination to maintain current capability and voltage rating.
The E1049-81 is rated for up to 636A continuous current and a voltage of 1000 Vac/dc. It is designed for 313 kcmil copper conductors with a female contact configuration. This high-amperage capability supports large motors and feeders, while the 1000 Vac/dc rating allows use across mixed AC and DC power systems in industrial settings.
Yes. The plug is classified for Ordinary/Non-Hazardous Locations and conforms to NEC/CEC standards with a NEMA 3 rating, enabling outdoor or semi-exposed installations subject to moisture or dust. This makes it suitable for loading docks, outdoor panels, and general industrial environments without specialized hazardous-area equipment.
Industries such as manufacturing, mining, material handling, oil and gas infrastructure, and heavy equipment fleets benefit from the E1049-81. Its 313 kcmil conductor capacity and 636A rating support large motor drives and power distribution circuits, while the rugged rubber housing and copper contacts ensure long-term reliability in vibration-heavy settings and outdoor environments.
Expect reduced maintenance points due to a rugged rubber housing and robust copper contacts that resist wear in vibration and moisture. The option for hexagon crimp or solder terminations speeds installation and reduces downtime. Fewer connectors and durable terminations translate to lower lifecycle costs and improved uptime for critical motor and feeder circuits.
