Eaton Crouse-Hinds E0400-165 Posi-Lok plug - 400A/600V

High current capability and voltage rating are built into the E0400-165, delivering up to 400A continuous at 600 Vac/dc. This means fewer terminations and a reduced risk of junction failures in motors and power feeders, cutting maintenance overhead. It is designed for 3/0-4/0 AWG conductors, making it a straightforward fit for large-panel startups and retrofit projects. Crimp termination with Posi-Lok engagement provides a vibration-resistant, lock-in-place electrical interface. The robust crimp path minimizes looseness due to equipment vibration, improving reliability in washdown and outdoor environments. This plug is ideal for panel-mounted connections in new builds or upgrades, accelerating assembly in manufacturing lines. Thermoplastic elastomer housing offers chemical resistance, weather tolerance, and a durable grip under field conditions. The blue color aids identification during large builds and service work, reducing mis-matches. The TPE body supports temperature variations and contributes to long service life in industrial settings. NEC/CEC compliance and Ordinary/Non-Hazardous area classification simplify regulatory clearance and end-user acceptance, while aligning with Eaton's Posi-Lok ecosystem for modular, scalable panel builds. Size and weight are optimized for standard enclosures: length 6.39 in, height 6.97 in, width 19 in, weight 2.82 lb, enabling straightforward layout planning and inventory management for control rooms and production lines.
