Eaton FLB362 TT70 3 Circuit Breaker - Hazardous Locations
Part Number: FLB362 TT70 3
Quick Summary
The Eaton FLB362 TT70 3 circuit breaker provides reliable protection for hazardous-location electrical systems in industrial plants. Operators face downtime when breakers trip unreliably in explosive environments, so robust construction and precise thermal-magnetic operation reduce risk and maintenance costs. It carries NEC/CEC compliance and hazardous-location ratings (Class I, Division 1; Class II, Division 1) plus NEMA ratings 3, 4, 7, 9. Designed for 600 Vac, three-pole service with threaded cover and copper-free aluminum enclosure, it fits standard 1-1/2 in trade-size installations. In practice, this translates to safer startups, easier field retrofit, and lower total cost of ownership for facilities handling flammable or pressurized processes.

FAQs
Plan for enclosure compatibility and mounting in Class I Division 1 or II locations. The unit uses a threaded cover for reliable sealing and a 1-1/2 in trade-size mounting footprint, aligning with standard panels. Verify panel clearances, torque requirements, and wiring methods per installation sheets, ensuring conduit seals and grounding meet NEC/CEC hazardous-location rules.
Rated for 70 A continuous current at 600 Vac, this three-pole, thermal-magnetic breaker uses a TED frame with threaded cover. It features a non-interchangeable trip and is designed for 1-1/2 in enclosure openings. Suitable for hazardous locations with NEC/CEC compliance and corresponding NEMA ratings for robust protection.
Best suited for hazardous-location applications in oil, gas, chemical processing, and mining facilities. It protects large-magnitude loads in 600 Vac distribution paths, where explosion-proof construction and reliable fault clearing are essential for safety and uptime, while integrating with standard switchgear and panels.
The breaker is NEC/CEC compliant and carries hazardous-location ratings (Class I, Division 1; Class II, Division 1) with corresponding NEMA ratings 3, 4, 7, 9. These certifications support compliant installations in hazardous environments and help streamline procurement and audit processes.
Non-interchangeable trip reduces the risk of improper replacements, while robust threaded-cover design and copper-free aluminum enclosure improve longevity and corrosion resistance. The result is lower maintenance costs, reduced downtime, and a favorable total cost of ownership across hazardous-location facilities.
