Eaton TP664 Steel Switch Box - NEC/CEC Certified, 14 cu in
Part Number: TP664
Quick Summary
Eaton TP664 Switch Box delivers rugged steel enclosure protection for electrical controls in industrial panels. In tight installations, engineers often wrestle with limited space, awkward knockouts, and wiring congestion that slows assembly and increases risk. It carries NEC/CEC compliance, UL certification for steel switch boxes, and ordinary/non-hazardous area classification to keep installations safe and code-compliant. Designed for control panels, motor starters, and automation cabinets, the TP664 uses NM clamps, 2-cable knockouts, and a gangable configuration to maximize space, simplify routing, and allow future expansion with minimal hardware changes. This combination reduces installation time and maintenance costs while improving reliability in harsh industrial environments.
