FAQs
AREX4041212 is designed for panel-mounted installations within industrial enclosures. Plan for a footprint of 23.63 in length and 19.31 in height, and support for its 61.6 lb weight. Ensure proper cable routing for a 1.25 in wire well, maintain clearance for the spring door, and follow NEC/CEC grounding and wiring rules for a safe, compliant setup.
AREX4041212 provides 400A, 600 Vac/250 Vdc, and 50–400 Hz operation with a three-wire, four-pole configuration and Style 1 grounding. It is rated for Ordinary/Non-Hazardous Locations, aligning with NEC/CEC standards to support safe, reliable power distribution in standard industrial facilities.
Yes. AREX4041212 is part of the Arktite 400A family and uses a 5" trade size, designed to integrate with other Arktite components. For fit verification, consult the provided 3D CAD drawing package and catalog pages to ensure mounting clearance and wiring compatibility across your system.
The Spring door design speeds access to terminations while maintaining a tight seal against dust and moisture. This reduces ingress-driven wear and simplifies routine inspections or replacements, helping minimize maintenance-induced downtime in harsh environments.
The combination of a copper-free aluminum body, high current rating, and NEC/CEC compliance lowers total cost of ownership by reducing corrosion-related failures, downtime, and spare parts inventory. Lighter weight also lowers installation labor, while compatibility with Arktite catalogs ensures scalable, future-proof power distribution in demanding facilities.
