Eaton Specification Sheet - 545A
Copper-free aluminum construction provides corrosion resistance and lighter handling, reducing installation labor and transport costs. This material choice supports easier installation in tight spaces and rugged environments while maintaining long-term durability. IP66 ingress protection safeguards against dust and powerful water jets, improving enclosure reliability in outdoor, washdown, or dusty facilities and minimizing unscheduled downtime. The 4.5 in depth, 4.5 in height, and 3 in width, combined with a surface-mount design, enable straightforward mounting in existing panels and equipment housings, reducing retrofit time and permitting rapid project execution. Compliance with NEC/CEC standards and Ordinary/Non-Hazardous Locations classification simplifies procurement and regulatory alignment, lowering the risk of nonconformant installations and speeding up approvals. At 2.2 lb, this copper-free aluminum box offers a practical balance of strength and weight, enhancing handling during installation and field servicing. The Pauluhn 545A family compatibility ensures wide accessory availability and future expansion without enclosure changes, supporting lifecycle planning and spare-part readiness. Overall, the 545A delivers a reliable, cost-effective solution for typical industrial environments where space, protection, and ease of installation matter.

FAQs
The 545A is specifically designed as a surface-mount junction box, offering a compact footprint (3 in wide, 4.5 in height and depth) that fits standard panel openings. Its copper-free aluminum construction keeps weight manageable for rework or additions, while still providing robust protection in typical plant environments. This makes it straightforward to integrate with existing panel layouts and wiring schemes without reconfiguring enclosure space.
IP66 protection means the enclosure resists dust ingress and withstands powerful water jets from any direction. This level of sealing is ideal for outdoor installations, washdown areas, and harsh indoor spaces where moisture and particulates are a concern. Designers can rely on the 545A to protect terminations and maintain performance under demanding operating conditions.
Yes. The 545A is certified for Ordinary/Non-Hazardous Locations under NEC/CEC standards. This classification covers most standard manufacturing floors, mechanical rooms, and general electrical cabinets, enabling compliant procurement and streamlined approvals without special explosion-proof or hazardous-area considerations.
The enclosure is made from copper-free aluminum, providing corrosion resistance with a lighter weight of about 2.2 lb. This combination improves transport, installation speed, and energy efficiency on site. The material choice also reduces maintenance needs over the life of the installation and helps with long-term reliability in variable environments.
