Eaton TP137 Steel Switch Box - 10.5 cu in, NEC/CEC
Part Number: TP137
Quick Summary
Eaton TP137 Steel Switch Box safely houses outlets and switches in ordinary locations. When space is tight and conduit entries crowd the panel, traditional boxes slow progress and can complicate wiring. This model meets NEC/CEC requirements and carries UL Canada certification, plus an area rating for Ordinary/Non-Hazardous Locations, giving you confidence in field installations. Its gangable design and through-beveled corners streamline installations for contractors and maintenance crews alike, reducing on-site time and service interruptions. By combining rugged steel construction with practical features, TP137 delivers predictable performance, long service life, and a lower total cost of ownership for commercial, industrial, and service environments.

TP137 uses heavy-duty steel to resist impact and corrosion, delivering a reliable 10.5 cubic inch capacity that accommodates multiple conductors. This drives a measurable business impact: fewer field adjustments, safer terminations, and longer service life in harsh environments. The application spans standard electrical rooms and equipment cabinets where space is at a premium and code compliance is non-negotiable. Through-beveled corners and clamps for entry improve conduit alignment and simplify installation. The resulting business impact is faster wiring, fewer mis-threads or nicks, and tighter seals against dust and moisture, even when working in tight spaces or during retrofit projects. The gangable design, along with ears and Hold-tite, lets you assemble multiple boxes into larger enclosures without bulky hardware, reducing inventory complexity and enabling scalable solutions for growing machine lines. Conduit and cable entry through one 1/2 in bottom knockout and two cable knockouts provides flexible routing options for feeders and control wiring, translating into lower labor costs and quicker commissioning. Compliance and certifications — NEC/CEC standards, Ordinary/Non-Hazardous area rating, and UL Canada certification — support regulatory alignment and risk management in audits.
