FAQs
The FLB221 TT30 2 is designed for Class I and II hazardous locations (Divisions 1 and 2) and Class III environments, with additional NEMA ratings 3, 4, 7, and 9. It is ideal for control panels in chemical processing, oil and gas facilities, and other harsh environments where explosion-protected performance and UL-listed protection are required. Its threaded cover and copper-free aluminum enclosure facilitate secure installation in confined spaces.
Key specs include a 30 A amperage rating, two-pole operation, 1 inch trade size, TE B frame, thermal-magnetic trip, and a voltage rating of 240 Vac or 125–250 Vdc. The enclosure is copper-free aluminum with a threaded cover, and the unit is designed as part of the Eaton FLB explosionproof circuit breakers family, offering reliable protection in hazardous locations.
Yes. The FLB221 TT30 2 is NEC/CEC compliant and UL-listed for use in hazardous locations. It carries NEMA ratings 3, 4, 7, and 9, supporting safe operation in demanding environments such as chemical plants, oil refineries, and other installations requiring explosion-protected equipment and regulatory compliance.
The enclosure uses copper-free aluminum with a threaded cover, reducing weight, improving corrosion resistance, and simplifying field maintenance. This design supports easier cable routing, secure sealing in hazardous environments, and faster retrofits or replacements in multiple panel configurations.
The FLB221 TT30 2 delivers predictable, reliable protection with reduced nuisance trips thanks to thermal-magnetic technology, lowering unplanned downtime. Its robust construction and certified compliance minimize audit findings and rework, while longer service life and easier installation lower lifecycle costs in high-hazard applications.
