Thermal magnetic protection delivers fast, selective tripping for overloads and short circuits, reducing downtime and collateral damage in critical loads. This ensures safer operation in hazardous environments and helps you meet NEC/CEC requirements while maintaining NEMA ratings. The threaded enclosure cover minimizes ingress in dusty or damp conditions, improving long-term reliability in field installations. The copper-free aluminum enclosure keeps weight manageable and enhances corrosion resistance, supporting safer handling and easier mounting in tight spaces. With a 1-1/2" trade size and a two-pole design, integration with standard switchgear is straightforward, saving panel real estate and simplifying wiring. The non-interchangeable trip reduces misconfiguration in the field, while providing consistent protection across equipment. Combine this with the TEFB frame type for compatibility with Eaton's FLB family, enabling predictable maintenance cycles and reduced total cost of ownership. In addition, the product line supports rugged industrial electrical protection in hazardous locations such as Class I, Division 1, and Division 2 environments, helping engineers achieve reliable safety compliance.

FAQs
The FLB223 TT90 2 uses a threaded enclosure cover and a copper-free aluminum enclosure designed for rugged field installation. It is a two-pole unit with a 1-1/2" trade size, enabling straightforward mounting in standard switchgear and control panels. It is intended for Hazardous/Classified Locations and supports NEC/CEC compliance, ensuring proper enclosure integrity in Class I, Division 1/2 environments.
This model provides a 90 A amperage rating with a two-pole configuration and a thermal-magnetic trip. It supports a voltage rating of 240 Vac/125-250 Vdc and follows the TE B frame type with a 1-1/2" trade size. The device is suitable for use in hazardous locations and adheres to NEC/CEC standards, with NEMA ratings 3, 4, 7, 9 for protective enclosure performance.
The FLB223 TT90 2 has a non-interchangeable trip, meaning the protective trip setting cannot be swapped. This provides consistent protection across installations but may require selecting different model variants for varying protection levels. For applications needing adjustable or interchangeable trips, consider alternative frame types within the FLB line.
The unit is certified for Hazardous/Classified Locations and conforms to NEC/CEC standards. It carries NEMA ratings of 3, 4, 7, and 9, reflecting suitability for a wide range of environmental conditions. Installation in hazardous area panels is supported by these certifications, and Canada-related certifications are accessible via Eaton/UL documentation linked in the product page.
Refer to Eaton’s IF 1016 instruction sheet and the FLB datasheet for installation steps, torque recommendations, and wiring guidance. Use proper enclosure sealing, confirm the 1-1/2" trade size fits the panel cutout, and verify copper-free aluminum enclosure integrity. Regular inspections should focus on enclosure sealing, tightening torque, and ensuring the non-interchangeable trip remains intact to preserve protection parity.
