Eaton Specification Sheet - WIUM1W1
Die-cast aluminum construction delivers durable, corrosion-resistant protection for industrial panels, reducing replacement frequency and maintenance costs while maintaining a clean, professional enclosure. This enables longer mean time between failures (MTBF) and greater uptime in demanding environments. The 2.25 inch depth, 6 inch length, and 4.1 inch width provide reliable fit and seal across a wide range of single-gang boxes, with a 16:1 configuration that supports inserts and movable hinges for flexible mounting. Universal mounting and the option for horizontal or vertical installation simplify logistics, lowering spare-parts inventory and enabling quicker field retrofits. The NEMA 3R rating and NEC/CEC compliance offer essential protection for both indoor and outdoor locations, ensuring safety and code conformity during energized operation. Together, these features translate into lower installation time, reduced risk of non-compliance, and improved lifecycle value for control panels in manufacturing and process industries.
