Eaton FLB116 WT100 3 - Thermal Magnetic, Explosionproof

100 A amperage rating with a three-pole design (600 Vac) delivers targeted feeder protection and precise fault isolation, reducing energy waste and minimizing downtime on motor circuits in demanding environments. This translates to lower maintenance costs and higher overall equipment effectiveness for critical processes in oil, gas, chemical, and other hazardous facilities. Frame type and construction are optimized for fast, compatible installation in Eaton/Crouse-Hinds systems. The FDB frame type and threaded enclosure cover enable straightforward field servicing in tight electrical rooms and in corrosive atmospheres. Practitioners benefit from simpler replacement and reduced commissioning time, which translates into lower project risk and faster ROI during upgrades or expansions of hazardous-location power distribution. Copper-free aluminum enclosure reduces weight and corrosion risk, improving handling and longevity in harsh environments. This material choice supports lower installation labor and longer service intervals, while maintaining rugged mechanical strength. Hazardous-location ratings and NEMA protections (3, 4, 7, 9) provide confidence that equipment remains safe and compliant across a range of climates and hazard profiles, from offshore platforms to chemical processing facilities. Non-interchangeable trip prevents misconfiguration and unintended changes to protective settings, a critical control for safety-critical circuits. With NEC/CEC compliance and Class I/II/III ratings, engineers can document code conformance easily during audits. The 100 A, 3-pole design is suitable for main feeders and branch circuits in hazardous areas, and its 1-1/2 inch trade size supports standard panel layouts. This combination delivers predictable protection, reduced risk, and a clear path to regulatory compliance in industrial installations. Compatibility with the FLB series ensures future expandability; the unit integrates with standard Eaton/Crouse-Hinds installation practices and UL-listed components. This reduces obsolescence risk and streamlines procurement for large projects. In practice, technicians appreciate clear labeling, easy testing, and predictable response under fault conditions, which together lower total cost of ownership in hazardous-location electrical systems.
