FAQs
When installing the FLB141 WT30 3 in hazardous locations, ensure it resides in an explosion-proof enclosure compatible with the Crouse-Hinds FLB series. Use the threaded cover for service access and follow the IF1016 instruction sheet for mounting, wiring, and torque specs. The unit is a three-pole device rated for 480 Vac and 30 A, designed for Class I/II/III environments.
Key ratings include 30 A amperage, three poles, and a 480 Vac voltage rating. The device uses a thermal-magnetic trip mechanism and features a 1-1/4" trade size within the EHD frame. These specs support reliable protection for motor feeders and distribution circuits in hazardous-location installations.
Yes. The FLB141 WT30 3 carries NEC/CEC compliance and is rated for Hazardous/Classified Locations, including Class I Division 1 and Division 2, as well as Class II/III. It also aligns with typical NEMA configurations (3, 4, 7, 9) to support robust protection in industrial control panels exposed to hazardous atmospheres.
This breaker is part of the FLB explosion-proof family and uses the EHD frame with threaded enclosure cover, aligning with FLB installation practices. For compatibility and safe integration, reference the FLB catalog, the IF1016 instruction sheet, and the Eaton specification sheet to ensure proper mounting, wiring, and enclosure selection for your panel design.
Choosing this breaker enhances safety and reliability in hazardous environments, reduces downtime through precise thermal-magnetic protection, and simplifies compliance with NEC/CEC and NEMA ratings. Its copper-free aluminum enclosure lowers weight and corrosion risk, while non-interchangeable trips reduce misconfiguration, delivering predictable performance and favorable total cost of ownership in critical facilities.
