Eaton TP431SSB Square Outlet Box - 30.3 cu in
Part Number: TP431SSB
Quick Summary
Eaton TP431SSB is a square outlet box designed for durable electrical junctions in industrial enclosures. When wiring in harsh environments, users often contend with limited knockouts, awkward conduit options, and the risk of ingress compromising enclosure integrity. This box meets NEC/CEC standards for ordinary locations and holds UL-certified steel construction, delivering reliable performance and long service life. Coupled with a 4-inch size and a 30.3 cubic inch capacity, it supports efficient, compliant installations. For engineers and technicians, it translates into fewer field modifications, faster panel assembly, and predictable compatibility with standard covers while maintaining robust protection for critical control circuitry.

FAQs
Begin by selecting the appropriate side or bottom knockouts for the wiring practice, install the AC/MC clamps, secure the conduit, and then route conductors to the terminal points. Use the welded steel body for rigidity, ensuring the cover aligns flush with the enclosure. This approach minimizes insulation damage and reduces rework during panel builds.
The TP431SSB is a 4-inch square outlet box with a 30.3 cubic inch interior capacity, welded steel construction, and side knockouts including four 1/2 in, two 1/2 in, and one 3/4 in E, plus a 1/2 in bottom knockout. It uses AC/MC clamps for conduit attachment and has dimensions of 4 in by 4 in by 2-1/8 in.
The TP431SSB is specified for Ordinary/Non-Hazardous Locations under NEC/CEC standards. It is not intended for use in Hazardous (classified) environments. If your application requires hazardous-location ratings, select an enclosure rated for those conditions and consult applicable UL or NEC guidelines.
The TP431SSB conforms to NEC/CEC standards for ordinary locations and benefits from UL certification for steel square outlet boxes. This combination supports regulatory compliance in most industrial settings and simplifies inspection and documentation in maintenance programs.
With its 4-inch form factor, ample 30.3 cu in capacity, welded steel construction, and multiple knockouts, the TP431SSB enables faster wiring layouts and fewer field modifications. The AC/MC clamps streamline conduit connections, reducing parts handling time and rework, which translates into lower labor costs and shorter downtime during panel assembly.
