AJ82 delivers a sequence of value-driven benefits tailored to industrial power enclosures. First, the 400A current rating enables high-load distribution within a single, compact box, reducing the number of enclosures required and shortening panel wiring diagrams for faster installations. This translates to measurable labor savings and improved project timelines. The cast aluminum construction provides excellent corrosion resistance and structural integrity, which lowers maintenance costs and extends service life in demanding factory floors and environmental enclosures. The 11.81 in L x 11.63 in H x 9 in W footprint, paired with a 4.65 lb weight, offers a practical balance of durability and ease of handling for installation teams working in tight spaces. With a one hub back box design, conduit routing is simplified, streamlining field terminations and reducing the chance of wiring errors. Compliance with Ordinary/Non-Hazardous Locations helps satisfy regulatory requirements while avoiding unnecessary over-engineering for standard facilities. The AJ82 also supports standard 3" trade-size devices, promoting compatibility with a broad range of switches, receptacles, and modular components, which can lower procurement complexity and inventory costs. Installation and retrofit scenarios benefit from straightforward mounting versus larger multi-gang options, enabling faster upgrades during plant modernization or expansion projects. Finally, the durable enclosure aligns with best practices in electrical infrastructure for industrial automation, enabling predictable performance and long-term ROI.
