Eaton FLB141 TT15 3 Circuit Breaker - UL Hazardous Location
Part Number: FLB141 TT15 3
Quick Summary
FLB141 TT15 3 circuit breaker provides reliable overcurrent protection for hazardous-location three-phase 480 Vac systems. Choosing a breaker not engineered for hazardous environments can lead to costly maintenance, corrosion, and unexpected downtime. UL-certified, NEC/CEC listed, and rated for Hazardous/Classified Locations (Class I/II/III), this unit ensures compliance and safe operation in demanding facilities. Its TED frame and threaded cover strike a balance between rugged protection and serviceability, enabling simpler retrofits and faster installs. In addition, copper-free aluminum construction and a non-interchangeable trip reduce long-term lifecycle risk, while the 15 A rating aligns with motor and feeder protection needs in industrial plants. For engineers seeking reliability and compliance, this solution supports efficient panel builds and lowers total cost of ownership.

Eaton Specification Sheet - FLB141 TT15 3
Feature is thermal-magnetic trip with 15 A rating, 480 Vac capability, three-pole configuration, and TED frame design. Business Impact is precise, predictable overcurrent protection for large, three-phase motors and feeders in demanding environments, reducing nuisance trips and improving uptime. Application is industrial power distribution where quick, dependable protection is critical. The second feature is threaded cover construction with copper-free aluminum enclosure, providing rugged, corrosion-resistant protection that simplifies field service and maintenance in harsh locations. The business impact is extended service life and easier sealing against dust and moisture, lowering maintenance costs and downtime. Application includes offshore, chemical, and mining facilities where exposure to corrosive atmospheres is common. The third feature is non-interchangeable trip with a fixed coordination profile, delivering consistent protection and preventing misconfiguration. The business impact is enhanced safety and regulatory compliance, especially for critical loads such as pumps and compressors. Application spans safety-critical plant sections and emergency circuits. The fourth feature emphasizes enclosure with circuit breaker and a 46 lb weight, offering stable installation in floor-standing panels and retrofit projects. The business impact is reduced installation time and greater rigidity in panel assemblies, improving overall project timelines. Application is any industrial control cabinet requiring durable, code-compliant protection. The fifth feature highlights NEC/CEC alignment, hazardous-location area classification, and NEMA ratings of 3, 4, 7, 9, which translates to broad compliance and rugged performance. The business impact is easier regulatory approval, safer outdoor or harsh-environment installations, and fewer costly redesigns. Application includes chemical plants, oil refineries, and remote mining sites. The sixth feature notes the 8.5 in depth, 13.38 in height, and 9.13 in width footprint, enabling precise space planning and compatibility with existing panels. The business impact is optimized enclosure utilization and faster installs in retrofit scenarios. Application covers standard industrial enclosures and new-builds requiring robust, code-compliant circuit protection.

FAQs
When installing the FLB141 TT15 3 in hazardous locations, ensure the enclosure is rated for Class I/II/III environments and is used with the threaded cover for sealing integrity. Verify wiring practices for copper-free aluminum conductors and maintain a clean, unobstructed panel to minimize heat buildup and keep the trip mechanism accessible for future maintenance.
The thermal magnetic trip provides both instantaneous overload and long-term overcurrent protection. The magnetic element handles short-circuit events while the thermal element reacts to sustained overloads, helping prevent motor burnout and protecting downstream conductors in 480 Vac, three-phase circuits typical of industrial motors.
Yes. The unit uses the TED frame type and a 1-1/4 inch trade size, designed to fit in panels built for TEFT/TED-type breakers. Its three-pole arrangement and threaded enclosure cover simplify mounting, making retrofits or new installations straightforward in standard control cabinets.
The FLB141 TT15 3 is UL-certified and NEC/CEC listed, with hazard-location ratings for Class I/II/III and NEMA ratings of 3, 4, 7, and 9. These certifications support compliance for installations in hazardous environments such as chemical plants, refineries, and mining operations.
The copper-free aluminum enclosure and threaded cover design minimize corrosion and ingress, reducing maintenance cycles. The non-interchangeable trip reduces the risk of incorrect replacement, while the rugged TED frame supports durable, long-term reliability in harsh conditions, lowering total cost of ownership over the equipment lifecycle.
