FAQs
The FLB222 TT15 3 is a three-pole, 1-1/4" trade size breaker designed to fit TE B frame enclosures with threaded covers. It is copper-free aluminum and intended for use in Class I, II, III environments per NEC/CEC. When wiring, ensure compliance with local hazardous-location codes and torque specs from the installation sheet to maintain certification integrity.
The thermal magnetic trip provides precise overload and short-circuit protection with a non-interchangeable trip curve, ensuring predictable tripping behavior under fault conditions. This reduces nuisance trips, improves system stability, and supports safer shutdowns in demanding environments like refineries and chemical plants.
Yes. The unit is rated for 240 V AC and 15 A, three-pole operation, matching typical low-voltage distribution needs in hazardous locations. Its TE B frame and 1-1/4" trade size enable straightforward integration into standard panel schedules, while the threaded cover aids field maintenance without compromising enclosure integrity.
This model aligns with NEC/CEC requirements and UL certifications for explosion-proof equipment, with NEMA ratings 3, 4, 7, 9. It also supports area classifications for Hazardous/Classified Locations, easing procurement and compliance reviews in regulated industries such as oil & gas, chemical processing, and mining.
The rugged copper-free aluminum enclosure, robust TE B frame, and reliable thermal magnetic trip reduce downtime and maintenance costs in hazardous zones. Enhanced protection translates to fewer unplanned outages, longer service intervals, and lower lifecycle costs, delivering a favorable ROI over traditional open-frame breakers in demanding plants.
