Eaton Posi-Lok E0400-157 Plug - Up to 400A, NEC/CEC

High-current capacity and conductor flexibility define the E0400-157 plug. It supports up to 400 A continuous with #2-2/0 AWG conductors, rated for 600 Vac/dc, enabling a single connector to feed large motors, drives, and power distribution blocks without the need for parallel splices. This reduces space, simplifies wiring diagrams, and minimizes heat buildup at terminations, which translates to longer component life and lower maintenance costs in demanding environments such as packaging lines, material handling, and process automation. Double set screw connections deliver a robust mechanical bite that resists loosening under vibration and frequent cycling. The interface remains stable during start-stop duty, thermal expansion, or external shocks, reducing reboot times and eliminating intermittent faults common with friction-fit terminations. This reliability supports continuous operation in conveyors, robotic cells, and outdoor enclosures, where downtime directly impacts throughput and service costs. Thermoplastic elastomer (TPE) housing provides impact resistance and flexibility for field terminations, while the vivid orange color enhances visibility during harnessing and maintenance. The material choice offers chemical resistance and temperature tolerance without cracking, helping technicians assemble correctly in tight spaces and reducing the risk of damage from incidental contact in busy industrial environments. Physical footprint and mating compatibility further streamline installations. The plug measures 6.39 in long, 6.97 in high, and 19 in wide, fitting standard enclosures and mounting patterns. It mates with compatible Posi-Lok receptacles for rapid, correct connections, supported by official installation sheets EB 168 and the E0400-157 datasheet to guide field assembly. Compliance and safety are embedded in the design. The device adheres to NEC/CEC standards and is suited for Ordinary/Non-Hazardous Locations, reducing regulatory risk on diverse facilities. The combination of secure locking, durable materials, and clear identification lowers operator error and supports longer service intervals, delivering lower lifecycle costs for manufacturing, energy, and automation projects.
