FAQs
The FLB142 WT100 3 is designed for Class I and II hazardous locations and Class III environments, with NEC/CEC compliance and NEMA ratings 3/4/7/9. It supports 100 A, 480 Vac, three-pole installations and is suitable for control panels, MCCs, and equipment in chemical plants, refineries, and other demanding sites.
Yes. It features an EHD frame, threaded enclosure cover, and a copper-free aluminum housing, which improves installation ease, sealing integrity, and compatibility with typical low-voltage panels and explosion-protected enclosures in hazardous locations.
The FLB142 WT100 3 uses thermal-magnetic trip technology with a non-interchangeable trip. This provides consistent coordination and reduces the risk of mis-calibrated trips, simplifying maintenance planning and ensuring predictable response under overloads and faults.
It complies with NEC/CEC standards and is approved for Hazardous/Classified Locations (Class I, Division 2; Class II, Division 1; Class I, Division 1; Class II, Division 2; Class III), with NEMA ratings 3, 4, 7, and 9, making it suitable for regulated industrial environments.
Key benefits include enhanced safety and reliability in hazardous environments, reduced downtime due to fixed trip characteristics, corrosion resistance from copper-free aluminum, and simplified installation with an EHD frame. These factors contribute to lower total cost of ownership in challenging industrial applications.
