Eaton Specification Sheet - WIU1W1
Rugged polycarbonate construction delivers impact resistance and weather durability, reducing replacement costs in demanding environments while maintaining clear visibility of live components. This translates to fewer service calls and safer operation in daily maintenance tasks. The extra-duty while-in-use design preserves circuit integrity during energized service, minimizing downtime and permitting fast access for diagnostics without powering down the system. Universal mounting supports multiple panel configurations, enabling horizontal or vertical installation and simple retrofits across existing single-gang enclosures, which shortens installation cycles and lowers labor costs. The 16:1 configuration with inserts and movable hinges provides flexible faceplate customization, supporting a wide range of cover insert options and reducing spare-part inventory needs. NEMA 3R rating and NEC/CEC adherence underpin regulatory compliance and outdoor or semi-exposed usage, improving risk management and asset protection. The white polycarbonate body provides a clean, durable finish that resists UV exposure and cleans easily, contributing to lower maintenance and improved uptime in long-term operations.

FAQs
WIU1W1 supports universal mounting for single-gang enclosures and can be mounted in horizontal or vertical orientations. It uses inserts and movable hinges to achieve a 16:1 configuration, allowing customization to fit various cutouts. For installation, align the cover with the enclosure opening, secure with standard fasteners, and verify clearance with any attached faceplates. This flexibility reduces retrofit complexity and speeds up project timelines.
Key specifications include NEMA 3R rating for weather resistance, NEC/CEC standards compliance, and ordinary/non-hazardous area classification. The 6 in length, 4.1 in width, 2.64 in height, and 2.25 in depth provide ample clearance for wiring and inserts, while the polycarbonate body offers impact resistance and UV stability. Together, these features ensure reliable operation in industrial environments with ongoing live circuits.
Yes. The WIU1W1 is designed for ordinary/non-hazardous locations with a NEMA 3R rating, which supports protection against rain and moisture. Its extra-duty construction and polycarbonate material withstand impact and harsh cleaning regimes. The universal mounting and 16:1 configurability allow it to fit a broad range of control panels, making it a versatile choice for challenging environments.
WIU1W1 complies with NEC/CEC standards and carries a NEMA 3R rating for outdoor or semi-exposed use. The area classification of Ordinary/Non-Hazardous Locations further confirms suitability for typical industrial facilities. These certifications help ensure compliance during inspections and support safer, code-conforming installations across facilities.
The polycarbonate construction and sealed design minimize upkeep, resisting wear from exposure to dust, moisture, and cleaning agents. Its universal mounting reduces installation time and part variety, while the extra-duty, live-circuit protection lowers downtime and maintenance costs. Over time, these factors translate to improved uptime, lower replacement frequency, and a favorable return on investment for panel installations.
