FAQs
Yes. The FLB220 TT30 1 is certified for Hazardous/Classified Locations and supports NEC/CEC requirements with area classifications including Class I, Division 1 & 2, Class II, and Class III. It is designed to fit standard enclosures and uses a 3/4" trade size, making it compatible with typical panelboard and control enclosure configurations used in industrial plants.
The thermal-magnetic trip combines a thermal element for long-term overload protection with a magnetic element for instantaneous overload response. This dual mechanism provides selective tripping for overloads and short circuits, minimizing nuisance trips while ensuring fast isolation of faulted circuits in demanding environments.
Best-use scenarios include control panels, pump stations, and process areas in oil, gas, chemical, and mining facilities where dust, vibration, and corrosive exposure are common. The unit’s copper-free aluminum housing, threaded cover, and explosionproof construction support reliable performance and regulatory compliance in these environments.
The FLB220 TT30 1 meets NEC/CEC standards and carries NEMA ratings 3, 4, 7, and 9, with area classifications for Hazardous/Classified Locations. These certifications support safe operation, ease of regulatory documentation, and compatibility with national and regional electrical codes.
With a non-interchangeable trip feature, field replacement reduces misconfiguration risk and simplifies maintenance. The threaded cover and robust enclosure design enhance durability in challenging environments, translating to lower maintenance frequency, reduced downtime, and improved overall return on investment in hazardous-location installations.
