Eaton PFTA4 4Q1075 Ruff-IN Assembly - NEMA 1 NEC/CEC
Part Number: PFTA4 4Q1075
Quick Summary
The Eaton Crouse-Hinds Ruff-IN PFTA4 4Q1075 provides a rugged, 4" box for industrial control panels. Installing enclosures securely in tight, non-hazardous locations can be challenging due to mounting constraints and wiring density. It carries NEC/CEC standards, NEMA 1 rating, and Canadian certifications, giving engineers confidence in compliance across facilities. Designed for BBT-HF compatibility, raised mud ring mounting, and a robust welded construction, this Ruff-IN reduces field rework and speeds panel assembly. In practice, contractors appreciate the built-in clamps, multiple knockouts, and solid ground wire for straightforward, safe wiring. This combination supports faster commissioning, automated manufacturing workflows, and scalable panel layouts for growing facilities.
