Eaton FLB222 TT20 3 - Explosionproof 3-Pole Hazardous

The FLB222 TT20 3 delivers 20 A, three-pole thermal-magnetic protection, providing fast, reliable interruption on overloads and short circuits. This precise trip characteristic reduces nuisance trips on motor starts and parallel loads, improving overall line stability and protecting critical equipment from damaging fault currents. In hazardous-location installations, this performance translates into fewer unplanned outages and smoother maintenance windows, especially where motor control centers and distribution gear are densely packed or long feeder runs complicate fault diagnosis. Enclosure construction uses copper-free aluminum with threaded cover, delivering corrosion resistance and a lighter footprint for easier handling in field conditions. The threaded cover simplifies field service and resealing after inspections, while the copper-free material reduces weight without compromising strength. For outdoor or damp environments, these design choices support longer service life and lower maintenance costs. TE B frame type and 1-1/4" trade size align with common low-voltage gear footprints, enabling straightforward replacement and compatibility with existing Eaton/Crouse-Hinds distribution panels. This standardization minimizes engineering risk and spare-parts inventory while speeding up panel upgrades. The unit’s three-pole arrangement also ensures balanced protection for multi-phase feeders, which is critical in process lines and packaging equipment. Certifications and standards—NEC/CEC compliant, area classification for Hazardous/Classified Locations, and NEC hazardous rating coverage Class I Division 1 and 2, Class II Division 1 and 2, Class III, plus NEMA ratings 3, 4, 7, 9—reduce project risk by meeting regulatory requirements, easing audit processes, and aligning with safety programs in chemical, petrochemical, mining, and other high-risk sectors. Available installation resources—IF 1016 instruction sheet, Eaton specification sheet, and catalog pages—provide clear wiring diagrams, footprint details, and maintenance notes, accelerating commissioning and ongoing service. Customers also benefit from the included general specifications like 8.5 in depth, 13.38 in height, 9.13 in width, and 44 lb weight, which help in enclosure planning and rigging.
