Eaton Specification Sheet - FLB116 WT100 2
The FLB116 WT100 2 uses a thermal-magnetic, two-pole protection scheme in the FDB frame, delivering precise trip coordination and dependable main protection for 100 A circuits. This feature translates to fewer nuisance trips and improved system uptime in rugged industrial environments, particularly in hazardous locations where rapid response to overcurrent events is critical. The copper-free aluminum enclosure with threaded cover reduces weight and corrosion risk while simplifying field maintenance and resealing after inspections. By combining the enclosure with a certified circuit breaker, installation is streamlined, increasing installer efficiency and reducing the risk of mis-match components in critical control panels. The unit’s NEC/CEC compliance and NEMA ratings 3, 4, 7, and 9 provide regulatory confidence for petrochemical, mining, and other hazardous facilities, supporting safer commissioning and long-term reliability. The 1-1/2" trade size and 600 Vac/250 Vdc rating enable compatibility with standard industrial wiring practices, while the non-interchangeable trip ensures predictable performance across installed units.

FAQs
For proper deployment, ensure the unit is mounted in an enclosure rated for hazardous/classified locations and that the two-pole breaker is wired with 1-1/2 inch trade-size fittings. The threaded cover design aids secure sealing, while copper-free aluminum minimizes weight and corrosion. Always consult the installation sheet for torque specs and conductor sizing to meet NEC/CEC requirements.
Yes. The device is designed to meet NEC/CEC standards and is suitable for hazardous/classified locations. It features NEMA ratings 3, 4, 7, and 9, supporting operation in rugged environments. Certification documentation is available, including UL-related reports, to aid in regulatory audits and compliance documentation.
Key specs include a 100 A amperage rating, thermal-magnetic circuit protection, two-pole configuration, 600 Vac/250 Vdc voltage rating, and a 1-1/2" trade size. The frame type is FDB, with threaded enclosure cover and copper-free aluminum construction, designed for reliable operation in hazardous locations.
The threaded cover simplifies sealing and maintenance access, reducing commissioning time and leak risk in hazardous environments. Copper-free aluminum lowers weight and improves corrosion resistance, easing field handling and reducing installation labor. Together, these features support faster panel upgrades and streamlined servicing without compromising safety or compliance.
