Eaton Specification Sheet - FLB264 WT175 2
Thermal-magnetic two-pole design provides precise overcurrent protection and predictable trip curves, reducing nuisance trips and protecting critical equipment in harsh environments. This directly translates to fewer unscheduled outages and lower maintenance costs on hazardous-location panels. The threaded cover construction enhances enclosure integrity against dust, moisture, and corrosive atmospheres, simplifying field servicing and reducing commissioning risk in oil, gas, and chemical processing facilities. The copper-free aluminum enclosure offers lower weight and improved corrosion resistance, enabling easier installation, handling, and long-term durability in aggressive environments. A non-interchangeable trip feature prevents inadvertent cross-replacement, maintaining the device’s intended protection profile and simplifying spare-part management for plant engineers. Certifications including NEC/CEC compliance and NEMA ratings 3, 4, 7, 9 support regulatory adherence and project approvals in regulated industries. Comprehensive installation resources, instruction sheets, and a dedicated specification sheet streamline wiring, mounting, and startup, cutting commissioning time and enabling faster project completion.

FAQs
For hazardous-location installations, ensure the enclosure is mounted per OEM guidance, with the threaded cover secured to maintain enclosure integrity. Use copper-free aluminum enclosures and 2-pole thermal-magnetic protection configured for 600 Vac/250 Vdc. Refer to IF 1016 instruction sheets and the FLB specification sheet for wiring diagrams, torque specs, and clearance requirements.
Yes. The FLB264 WT175 2 is designed to meet NEC/CEC standards and supports area classifications for hazardous locations. It carries ratings appropriate for Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III environments, along with suitable NEMA ratings to ensure broad installation acceptance.
Key specs include a 175 A amperage rating, two-pole configuration, thermal-magnetic trip, 600 Vac/250 Vdc voltage rating, and a 2-1/2" trade size. It uses a JDB frame and a threaded enclosure cover with a copper-free aluminum body for durability and ease of installation in challenging environments.
The unit is supported by UL certification documents and Eaton’s installation resources, including the IF 1016 instruction sheet and the FLB264 WT175 2 specification sheet. Catalog pages and a dedicated datasheet provide deeper technical details to aid compliance and procurement.
Its robust threaded cover enclosure, corrosion-resistant copper-free aluminum body, and non-interchangeable trip design minimize risk of incorrect replacements and field rework. Coupled with NEC/CEC compliance and dedicated installation guides, the unit reduces commissioning time, downtime, and long-term maintenance costs in demanding industries.
