FAQs
The FLB264 WT175 3 uses a JDB frame and threaded enclosure cover designed for hazardous locations. Install by mounting in a compliant enclosure, wiring to the three-pole terminals, and securing the threaded cover to maintain integrity. Verify torque specs and conductor sizes per the Eaton installation sheet to ensure reliable operation.
This is a thermal-magnetic three-pole breaker with a 175 A rating and a 600 Vac voltage rating. The non-interchangeable trip provides predictable protection, while thermal-magnetic action limits nuisance trips during transient faults and overloads, supporting stable coordination in distribution panels.
Yes. The FLB264 WT175 3 is certified for Hazardous/Classified Locations, including Class I Division 1 where explosive atmospheres exist. Its enclosure and construction meet NEC/CEC requirements and NEMA ratings, making it appropriate for oil, gas, and chemical processing environments.
The unit carries NEC/CEC compliance, NEC hazardous ratings for Class I/II/III, and NEMA ratings 3, 4, 7, 9. It is designed for Hazardous/Classified Locations with threaded cover and copper-free aluminum construction, enabling regulatory-aligned installations and safer operation.
The non-interchangeable trip reduces misconfiguration, while the rugged copper-free aluminum enclosure lowers corrosion risk and weight. Integrated protection simplifies installation, reduces downtime during commissioning, and lowers long-term maintenance costs by delivering dependable performance in harsh environments.
