Eaton TP431SSBPF Square Outlet Box - NEC/CEC Certified
Part Number: TP431SSBPF
Quick Summary
The Eaton TP431SSBPF square outlet box provides a 4-inch enclosure for electrical connections in industrial control panels. Installers often struggle with knockout configurations, grounding continuity, and clamp compatibility, leading to longer installs and potential non-compliance. Certified to NEC/CEC standards with UL listings for ordinary locations, it supports US and Canada projects while meeting 30.3 in³ capacity. Its welded steel construction, ground screw with pigtail, and AC/MC clamps minimize installation steps and field adjustments. This translates to faster panel builds, consistent grounding, and reduced inventory needs across facilities. Engineers can rely on a standard 4-inch configuration that aligns with common enclosures, covers, and fittings.
