FAQs
The TP831 features eight side knockouts at 1/2 inch and four side knockouts at 3/4 inch, plus three bottom knockouts at 1/2 inch and two at 3/4 inch. This configuration supports flexible wiring routes and reduces the need for additional fittings, speeding installation and allowing neat, codes-compliant terminations in control panels.
Yes. The TP831 is built to NEC/CEC standards and carries UL certification for ordinary non-hazardous locations. This ensures regulatory compliance, improved safety, and easier approvals for most factory automation environments without special hazardous-location ratings.
The TP831 provides 30.3 cubic inches of internal capacity as a 4 inch square box with a depth of 2-1/8 inches. This space supports multiple conductors and devices, making it suitable for moderately complex automation panel terminations while maintaining code-compliant fill levels.
The air plenum feature promotes better air circulation within the enclosure, helping dissipate heat from mounted devices. This leads to lower operating temperatures, enhanced performance, and extended component life, particularly in densely packaged industrial control panels where heat is a constant concern.
The TP831’s conduit without clamps design reduces assembly time and field modifications. Combined with a drawn steel construction and 4 inch box size, it provides robust durability and faster installs in normal plant locations, delivering lower labor costs and quicker machine readiness for automation lines.
