FAQs
AREX40318 is designed for ordinary/Non-Hazardous Locations, aligning with NEC/CEC standards for general industrial power distribution. It features a 400 A rating and 600 Vac/250 Vdc capabilities, making it suitable for large motors, pumps, and process equipment in non-hazardous environments. The copper-free aluminum construction withstands washdowns and humid facilities without compromising strength.
With a 400 A rating and a voltage capability of 600 Vac/250 Vdc, AREX40318 supports heavy-duty feeder circuits and a frequency range of 50 to 400 Hz. The copper-free aluminum body provides durability while the spring-door frame ensures consistent contact performance. This combination reduces voltage drop and improves reliability in demanding drives and equipment.
AREX40318 carries NEC/CEC standard compliance and is specified for Ordinary/Non-Hazardous Locations as indicated by the area classification. This aligns with typical industrial facilities and ensures installations meet regulatory expectations. For projects requiring explicit isolation or hazardous location certifications, confirm compatibility with the Arktite AREX catalog pages.
Installers should plan around the 3 in trade size and the 0.84 in wire well to accommodate large conductors. The unit weighs about 61.6 lb, so lifting and mounting should use appropriate hardware. The spring-door design aids quick access, while copper-free aluminum reduces weight during handling. Follow NEC/CEC guidelines for non-hazardous locations.
Design teams can reference the AREX40318 3D CAD drawing package, the Arktite 400A catalog page, and installation sheets such as IF 352 documents for Model M72 variants. These resources help verify compatibility, plan wiring routes, and ensure proper mounting and safety compliance during deployment.
