Quick Summary
The Eaton Crouse-Hinds Posi-Lok E0400 plug provides secure, high-current power connections for heavy-duty distribution panels and equipment. Engineers often struggle with vibration-prone, unreliable assemblies that fail in demanding environments, causing downtime and costly field service. This plug is designed for Ordinary/Non-Hazardous locations and NEC/CEC compliance, helping facilities meet code while reducing risk. With the ability to accept 1/0-2/0 AWG conductors and a 600 Vac/dc rating, it supports up to 400 A continuous service. The thermoplastic elastomer (TPE) housing, combined with a crimp connection, offers weather resistance, accuracy in mating, and faster field termination—translating to lower labor costs and improved reliability on critical power feeds.

FAQs
For reliable terminations, use the crimp connection with 1/0-2/0 AWG conductors rated for up to 600 Vac/dc. Ensure proper mating with compatible E0400 panels, follow standard torque and crimp tooling practices, and verify lock engagement with the Posi-Lok mechanism after installation.
The E0400-143 is rated up to 400 A continuous and supports 600 Vac/dc, enabling heavy feeder and motor circuits. Its thermoplastic elastomer body offers environmental resistance, while the crimp termination provides a robust, vibration-resistant connection suitable for challenging plant conditions.
Yes. It is designed for Ordinary/Non-Hazardous Locations and NEC/CEC compliant installations, supporting 1/0-2/0 AWG conductors up to 400 A. It is well suited for non-hazardous industrial panels and distribution connections requiring reliable field terminations.
Consider NEC/CEC standards and the Ordinary/Non-Hazardous Locations classification. These indicate suitability for common industrial settings, with appropriate safety and performance expectations for 1/0-2/0 AWG cables and a 600 Vac/dc rating.
