FAQs
When installing the E0400-261, verify conductor size matches 3/0-4/0 AWG and prepare the conductors for a proper crimp termination using compatible tooling. Ensure the panel opening and enclosure space accommodate the 19 inch width and the 6.97 inch height, and confirm the connection remains within the Ordinary/Non-Hazardous Location specification. Use appropriate safety procedures for high-current terminations and inspect the green TPE housing for any signs of damage after installation.
The E0400-261 is rated for up to 400A continuous current and supports 600 Vac/dc, with crimp termination for 3/0-4/0 AWG conductors. This combination enables a compact, high-load feeder interface suitable for power distribution panels in non-hazardous industrial environments, reducing the need for multiple parallel connections while maintaining electrical integrity and reliability.
The plug is specified for Ordinary/Non-Hazardous Locations under NEC/CEC standards, which means it is appropriate for non-hazardous industrial and commercial environments. For hazardous area applications, consult a qualified engineer and use an enclosure and components rated for those conditions to ensure compliance and safety.
The crimp termination provides a robust, vibration-resistant connection that reduces loosening and rework. High-current capacity minimizes the number of joints, speeding up installation and future expansion. With a durable TPE housing and clear color-coding, it lowers inspection time and downtime, delivering a favorable total cost of ownership in power distribution applications.
The E0400-261 is designed for integration with Eaton Crouse-Hinds Posi-Lok panels and similar 19 inch wide enclosures. It supports 3/0-4/0 AWG conductors and a 600 Vac/dc rating, making it suitable for high-current feeders in power distribution panels. Ensure mating components are aligned, the crimp tooling is correct, and the overall installation adheres to NEC/CEC requirements for non-hazardous locations.
