Up to 400 A continuous amperage and a 600 Vac/dc rating define this plug's core capability, enabling it to handle demanding motor and power-distribution tasks without oversizing components. The physical footprint—6.39 in length, 6.97 in height, and 19 in width—supports reliable mating within standard enclosure layouts while preserving cabinet space for wiring. In practice, engineers gain predictable thermal performance and improved fault isolation, reducing the need for frequent recalibration or replacement in high-vibration industrial environments. Cable compatibility with #2-2/0 AWG conductors and a robust double-set-screw interface provide a secure, vibration-resistant interface, minimizing conductor movement under start-stop cycles and lowering resistance changes. This combination saves labor and enhances safety in panel terminations for motor control centers.

FAQs

Compatible with Eaton Crouse-Hinds Posi-Lok panels and large-diameter conductors, the E0400-256 accepts #2-2/0 AWG cables for up to 400 A continuous and 600 Vac/dc. The female plug uses a double-set-screw interface for secure, vibration-resistant mating. This combination supports reliable terminations in distribution panels and motor control centers, minimizing splices and rework.
Installation efficiency is improved by the plug’s secure double-set-screw design and its compact, predefined footprint. The E0400-256 eliminates loose connections that cause heat buildup and arcing, reducing field adjustments and downtime. In practice, technicians can complete terminations quickly, while manufacturers benefit from consistent electrical contact and predictable torque requirements across panels.
Yes. The E0400-256 is designed for Ordinary/Non-Hazardous Locations and aligns with NEC/CEC standards, simplifying procurement and compliance. Its 600 Vac/dc rating and #2-2/0 AWG cable compatibility support code-compliant terminations in many industrial facilities. This combination helps maintenance teams meet regulatory requirements while reducing risk from nonconforming connectors. In turn, it smooths audits and vendor qualification processes for electrical assemblies across manufacturing lines.
Plan for compatible, high-capacity terminations by using #2-2/0 AWG conductors and ensuring enclosure space supports a 6.39 in length, 6.97 in height, and 19 in width profile. The brown thermoplastic elastomer housing provides chemical resistance, while the double-set-screw interface supports secure mating under vibration. Follow NEC/CEC guidance and Eaton documentation for proper torque and mating procedures.
Using the E0400-256 can extend service life and lower maintenance costs by delivering repeatable, rugged connections that resist vibration and loosening. The double-set-screw design reduces rework, while the TPE body offers durable insulation in normal plant environments. This consistency translates into fewer field failures, quicker changes, and lower total cost of ownership across multi-line installations.
