Eaton Specification Sheet - FLB267 WT175 3
Thermal-magnetic overcurrent protection in a JD frame handles 175 A loads with precision, reducing nuisance trips and protecting downstream equipment. In mission-critical processes—oil & gas, chemical processing, mining—this translates to fewer process interruptions and longer motor life. Copper-free aluminum enclosure and threaded cover construction improve corrosion resistance and serviceability. Lighter weight simplifies lifting during installation and reduces technician fatigue on cramped or dusty sites; threaded covers enhance sealing against dust and moisture in harsh environments. NEC/CEC compliance and hazardous-location ratings (Class I, Division 1 and 2; Class II, Division 1 and 2; Class III) ensure regulatory alignment and safer audits, while NEMA ratings 3, 4, 7, 9 extend protection against weather and particulates for outdoor and indoor facilities. Interchangeable trip reduces spare parts inventory and downtime during scheme changes, enabling rapid protection updates without full breaker replacement. Three-pole, 3-inch trade-size, and 600 VAC rating align with Eaton’s Crouse-Hinds family, simplifying procurement and wiring while maintaining consistent installation practices across facilities. This combination supports lower total cost of ownership, improved uptime, and faster maintenance cycles across industrial sites.

FAQs
For hazardous-location installations, mount the three-pole FLB267 WT175 3 in a compatible enclosure using the JD frame and threaded enclosure cover. Verify 600 VAC rating and 175 A capacity prior to wiring. Use Eaton Crouse-Hinds accessories designed for the FLB series to ensure proper sealing, torque, and compliance with NEC/CEC requirements. Follow the installation sheet IF 1016 for step-by-step guidance.
The unit combines thermal-magnetic protection with a rugged JD frame, rated at 600 VAC for three-pole applications, and a copper-free aluminum enclosure. Its threaded cover improves sealing in dusty or humid sites, while interchangeable trip units reduce downtime when protection needs change. These features collectively enhance uptime, minimize unplanned maintenance, and support long service intervals in hazardous locations.
Yes. The FLB267 WT175 3 is explicitly rated for 600 VAC, three-pole operation and is designed for Hazardous/Classified Locations. It carries NEC/CEC compliance and supports Class I, II, and III ratings with appropriate NEMA protections, making it suitable for industrial sites that require explosion-proof protection and rigorous safety standards.
This breaker supports NEC/CEC compliance and hazardous-location certifications (Class I, Division 1 and 2; Class II, Division 1 and 2; Class III). It also carries NEMA ratings 3, 4, 7, 9, ensuring dependable performance in outdoor and harsh environments while meeting industry-audit expectations and regulatory requirements.
Interchangeable trips allow field protection adjustments without replacing the entire breaker, reducing spare parts inventories and downtime. This accelerates protection scheme updates as standards evolve or process needs change, delivering faster maintenance responses, lower total cost of ownership, and improved plant uptime over the equipment lifecycle.
