Eaton TP851 Square Cover - NEC/CEC Standards for Steel Box
Part Number: TP851
Quick Summary
Eaton TP851 Square Cover provides robust protection for 4-11/16 in steel square boxes used in industrial electrical installations. This accessory helps prevent dust, debris, and accidental contact while ensuring a clean, finished appearance in control panels. The design supports air plenum for modest ventilation, reducing heat buildup in compact enclosures. With NEC/CEC standards and area classifications suitable for Ordinary/Non-Hazardous Locations, TP851 supports compliant installations in commercial and light-industrial environments. By choosing a blank configuration in natural steel, engineers gain flexibility for future wiring or field modification without compromising enclosure integrity. This combination of durable steel construction, standard box size, and certification alignment translates to lower lifecycle costs and predictable procurement across projects.
