FAQs
Install the FLB223 TT90 3 within a suitable enclosure rated for hazardous environments, ensuring proper clearance and conduit ingress. The unit is a three-pole 90 A device with a TE B frame and threaded cover, designed for 240 V AC operation. Adhere to NEC/CEC requirements, use compatible NEMA-rated enclosures (3, 4, 7, 9), and verify Class I/II/III classifications for the specific location. This minimizes risk of arcing and ensures safe maintenance access.
The thermal-magnetic trip provides fast short-circuit interruption and thermal protection for long-running loads. The non-interchangeable trip reduces the chance of field mis-setting, improving protection reliability. This is especially important in hazardous locations where system downtime is costly and repair windows are limited, ensuring consistent discrimination and safer shutdowns under fault conditions.
Yes. The FLB223 TT90 3 is designed for Hazardous/Classified Locations with NEC/CEC compliance and is compatible with NEMA 3, 4, 7, and 9 enclosures. Its copper-free aluminum enclosure and threaded cover simplify sealing and serviceability, making it well-suited for explosion-proof panels in chemical plants, oil refineries, and mining environments.
This model carries NEC/CEC standards, Class I Division 1 and Division 2, Class II Division 1 and Division 2, and Class III ratings, along with NEMA ratings 3, 4, 7, and 9. It is intended for Hazardous/Classified Locations, aligning with international safety requirements and facilitating regulatory compliance, audits, and cross-border deployments.
The rugged copper-free aluminum enclosure and threaded cover design reduce corrosion risk and simplify maintenance. The non-interchangeable trip minimizes field calibration and replacement mistakes, lowering operational downtime and spare-parts costs. In practice, you gain longer service intervals, faster commissioning, and a lower total cost of ownership in hazardous-location installations.
