Eaton AREX403129 Receptacle Assembly - NEC/CEC
Part Number: AREX403129
Quick Summary
The Eaton Crouse-Hinds AREX403129 receptacle assembly delivers high-capacity power connections for Arktite enclosure systems in industrial facilities. A common pain point is wiring integrity in harsh environments, where corrosion and maintenance downtime erode productivity; AREX addresses this with copper-free aluminum and a rugged spring door. It complies with NEC/CEC standards for ordinary/non-hazardous locations and supports 50–400 Hz operation, 600 Vac/250 Vdc. The combination of performance and installation efficiency reduces lifecycle costs and simplifies procurement for panel builders and end users. Designed for durable, compliant power distribution in metal enclosures, AREX403129 helps keep critical processes running.

FAQs
AREX403129 is designed for Arktite AREX receptacle wells with a 3-1/2 inch trade size and copper-free aluminum construction. Plan for proper grounding (Style 1) and wiring within the 50–400 Hz, 600 Vac/250 Vdc rating. Ensure enclosure clearance, secure mounting, and adherence to NEC/CEC requirements during panel upgrades.
The device is rated for 400A, 600 Vac and 250 Vdc, operating from 50 to 400 Hz. It is a three-wire, three-pole receptacle with copper-free aluminum construction. These specs support large motor loads and high-current distributions in Arktite panels, enabling fewer feeders and simplified wiring while maintaining compliance and safety.
Yes, AREX403129 is classified for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards. This makes it appropriate for standard industrial environments where harsh environmental hazards are not present, streamlining procurement and installation within conventional manufacturing and processing facilities.
Procurement is supported by NEC/CEC certification, with installation and specification resources such as the Arktite catalog page for 400A plugs and receptacles, IF 853 installation sheets, and the Eaton AREX403129 datasheet. These provide compliance alignment, mounting guidance, and wiring instructions for safe, code-compliant installations.
Upgrading to AREX403129 can reduce panel count and wiring complexity, improving installation speed and uptime in heavy industrial environments. Eaton provides CAD drawings, installation instructions, and specification sheets to accelerate design and commissioning, contributing to lower lifecycle costs and faster project ROI through reliable, code-compliant distribution.
