Eaton Specification Sheet - FLB223 TT100 3
Feature → Business Impact → Application: The FLB223 TT100 3 is a 100 A thermal-magnetic circuit breaker, delivering precise overcurrent protection for feeders and motor circuits in demanding locations. This configuration translates to improved uptime and reduced outage costs in chemical plants, oil & gas facilities, and mining sites where hazardous classifications drive protection requirements. Application-wise, the 3-pole design supports balanced distribution for multi-line feeders, while 240 V AC operation aligns with common industrial control circuits. Feature → Business Impact → Application: The TEB frame with threaded enclosure cover provides rugged, code-compliant mounting in harsh environments, simplifying service access and sealing integrity in explosion-protected enclosures. This reduces maintenance time and helps sustain compliance during inspections in hazardous locations. Feature → Business Impact → Application: Copper-free aluminum enclosure minimizes weight without sacrificing strength, facilitating easier handling, installation, and retrofit projects in constrained plant spaces. Feature → Business Impact → Application: Non-interchangeable trip reduces mis-set protection, ensuring consistent protection settings across assemblies and lowering touchpoints for field technicians during maintenance. Feature → Business Impact → Application: Enclosure with circuit breaker, 1-1/2" trade size, and 8.5" length support straightforward integration into standard FLB series panels, enhancing compatibility and reducing through-panel adaptation. Feature → Business Impact → Application: NEC/CEC compliance and multi-class hazardous ratings (Class I–III) plus NEMA 3, 4, 7, 9 ensure reliable performance in a broad range of hazardous environments, meeting stringent industry standards and accelerating approval processes for new installations.

FAQs
The FLB223 TT100 3 is designed for hazardous/classified locations with NEC/CEC compliance and NEMA ratings 3, 4, 7, 9. Its 3-pole, 100 A configuration fits standard distribution panels in Eaton Crouse-Hinds FLB enclosures, while the threaded cover and copper-free aluminum enclosure support secure sealing and corrosion resistance in challenging environments.
Thermal-magnetic trip technology provides both long-time protection against overcurrent and instantaneous short-circuit protection. For the FLB223 TT100 3, this means reliable coordination with feeders and motors, reduced nuisance trips, and faster response to faults. The non-interchangeable trip design ensures consistent protection across installations, simplifying maintenance and reducing configuration errors.
This breaker carries NEC/CEC compliance and hazard-rated certifications for Class I, Division 1/2, Class II, Division 1/2, and Class III environments. It also aligns with NEMA ratings 3, 4, 7, and 9, supporting safe operation in a wide range of hazardous locations, chemical processing, and mining applications, with UL certifications documented in its product literature.
Key installation advantages include a threaded enclosure cover for secure sealing, a TEB frame that fits Eaton’s FLB series, and a copper-free aluminum enclosure that reduces weight. The 1-1/2" trade size and 8.5" depth enable integration into common panel footprints, while the 3-pole, 240 V AC configuration supports standard industrial wiring practices.
The non-interchangeable trip minimizes mis-coordination risks, reducing diagnostic time during maintenance. Its robust enclosure and hazardous-location certifications reduce downtime risk and compliance-related delays. With 45 lb weight and durable aluminum construction, installation and retrofits are quicker, delivering lower total cost of ownership in facilities with strict regulatory requirements.
