Eaton Specification Sheet - FLB223 TT70 3
Three-pole, 70 A rating with 240 V AC protection powers balanced three-phase loads with reliable coordination, improving fault isolation and panel reliability in process, chemical, and metalworking facilities. This enhances safety and uptime while reducing unexpected outages. The TE B frame and 1-1/2 inch trade size ensure compatibility with standard Eaton/Crouse-Hinds enclosures, minimizing retrofit costs and simplifying field installation in both new builds and upgrades. Threaded enclosure cover provides secure sealing and safer servicing in hazardous locations, supporting regulatory compliance and faster maintenance cycles. Copper-free aluminum enclosure reduces weight and corrosion risk, improving handling, outdoor installation viability, and long-term durability in coastal or chemical environments. Non-interchangeable trip offers fixed protection characteristics, reducing the risk of improper device substitution during maintenance. Certifications including NEC/CEC, Hazardous/Classified Locations, and NEMA ratings (3, 4, 7, 9) provide clear regulatory alignment for refinery, chemical plant, and energy facilities. This model aligns with the broader FLB family to optimize spare parts availability and reduce overall lifecycle costs while delivering reliable, explosion-protected protection for critical processes.
