Eaton PFTWFA 4Q1075 Ruff-IN Assembly - NEC/CEC
Part Number: PFTWFA 4Q1075
Quick Summary
Eaton Crouse-Hinds Ruff-IN assembly is a rugged, pre-fabricated electrical enclosure system designed for reliable outlet-box mounting in industrial facilities. Engineers often struggle with compatibility across stud spacing, knockout configurations, and mounting alignment in challenging environments. It aligns with NEC/CEC standards, carries a NEMA Rating of 1 for ordinary locations, and is UL-listed for Ruff-IN assemblies. For clients seeking faster installation and consistent performance, the wide-flange telescoping bracket and integrated MC connector streamline field setup. The design also accommodates 3- and 4-gang configurations and supports raised mud rings for better sealing and cable management. This translates to reduced field rework, faster turnarounds, and measurable cost savings over the project lifecycle.
