FAQs
Plan for a single-pole thermal-magnetic breaker with a 3/4 inch trade size in standard enclosures. The threaded cover simplifies sealing and inspection, while the copper-free aluminum enclosure resists corrosion in harsh environments. Verify enclosure ratings and mounting footprint match the TE B frame, and ensure wiring is compliant with NEC/CEC requirements for Class I and II locations.
It meets NEC/CEC standards and is rated for Hazardous/Classified Locations, including Class I Division 1 and 2, Class II Division 1 and 2, and Class III. NEMA ratings 3, 4, 7, and 9 apply, supporting safe operation in a range of hazardous environments and enabling compliant integration with control panels and switchgear.
Yes. The breaker is rated for 120 Vac and 125 Vdc, making it adaptable for mixed-power electrical architectures common in processing plants. This compatibility supports streamlined asset management and consistent protection across AC and DC circuits in hazardous locations.
Industries such as oil and gas, chemical processing, mining, and water/wastewater treatment benefit due to the combination of explosionproof construction, NEC/CEC compliance, and robust NEMA ratings. The FLB120- series offers reliable protection in hazardous areas where equipment must withstand corrosive environments and strict safety standards.
The non-interchangeable trip feature reduces the risk of tampering and misadjustment, ensuring consistent protection over time. Threaded covers and copper-free aluminum construction simplify inspections and corrosion resistance, lowering maintenance costs. Overall, this leads to improved uptime, safer operations, and predictable lifecycle costs for critical infrastructure.
