Eaton Specification Sheet - 527A
Copper-free aluminum construction provides excellent corrosion resistance and a lighter overall weight, translating to reduced maintenance intervals and lower handling costs on site. The business impact is clear: longer service life in coastal or industrial settings with less downtime due to corrosion, improving overall equipment reliability for control panels and field junctions. In practical applications, plants in offshore or chemical processing environments benefit from this material choice, enabling compliant, durable enclosures without the need for frequent replacements. IP66 ingress protection delivers robust dust and water resistance, reducing risk from washdowns and harsh weather. This enables uninterrupted operation in outdoor electrical infrastructures and exposed installations, cutting maintenance cycles and minimizing unplanned outages for mission-critical equipment. Surface-mount mounting simplifies installation on walls or equipment racks, decreasing install time and the need for specialized enclosures. The result is a faster, more repeatable deployment workflow with consistent sealing and mounting integrity across multiple assemblies. The enclosure’s dimensions (approximately 4.5 in length/depth by 4.5 in height and 2 in width) provide a compact footprint that fits neatly into standard control panels while leaving room for conductors and fittings. Lightweight construction (about 1.4 lb) reduces handling effort and shipping costs, supporting safer, more efficient installation crews. Compliance with NEC/CEC standards, along with suitability for ordinary/non-hazardous locations, ensures code-conformant protection without over-engineering the solution. Together, these features deliver a cost-effective, reliable enclosure that aligns with modern maintenance strategies and lifecycle management for industrial automation systems.
