Eaton FLB224 TT125 3 Circuit Breaker - Hazardous Locations
Part Number: FLB224 TT125 3
Quick Summary
Eaton FLB224 TT125 3 circuit breaker provides reliable protection for hazardous-location electrical systems in industrial facilities. Design teams often struggle with enclosure integrity, regulatory certification, and maintenance in explosive environments. This unit offers NEC/CEC compliance with hazardous ratings Class I Division 1 and 2, Class II Division 1 and 2, and Class III, plus UL listings and a rugged NEMA envelope for 3, 4, 7, and 9. For buyers, the combination of thread-covered enclosure and copper-free aluminum housing reduces corrosion risk and downtime, while a three-pole, 600 Vac thermal-magnetic trip supports safe coordination in three-phase systems. The FLB224 TT125 3 is well-suited for scalable protection in demanding industrial plants and process environments.

FAQs
For safe installation in hazardous environments, mount the three-pole unit in a threaded-cover enclosure made from copper-free aluminum. Verify adherence to NEC/CEC classifications, ensure proper clearance and cooling, and consult the IF1016 instruction sheet for wiring and grounding practices before commissioning.
Yes. The breaker carries NEC hazardous ratings (Class I Div 1/2, Class II Div 1/2, Class III) and UL certifications for explosionproof service, with a NEMA rating of 3, 4, 7, 9, making it suitable for hazardous-location installations and compliant with broad regulatory frameworks.
Ideal for chemical processing, oil and gas facilities, and other hazardous-location environments where three-phase protection is required. Its TFJ frame, 125 A rating, and 600 Vac capability support large motor loads and critical feeders while maintaining safety and compliance.
Rely on the non-interchangeable trip design for consistent protection and predictable replacement intervals. Schedule periodic inspection of the threaded enclosure and wiring terminations, and reference the IF1016 instruction sheet and Eaton’s specification sheet for service guidelines and torque values.
