FAQs
The FLB361 TT50 3 is designed for three-pole, 1-1/4" trade-size installations within TED frame platforms, featuring threaded enclosure covers and copper-free aluminum enclosures. It integrates with Crouse-Hinds FLB series and similar Eaton protection schemes, enabling straightforward mounting, standardized wiring interfaces, and cohesive protection coordination across hazardous-location circuits.
Key specs include a 50 A amperage rating, 600 Vac voltage rating, thermal-magnetic trip mechanism, and three-pole configuration. The unit uses a non-interchangeable trip, is designed for 1-1/4" trade size, and operates within the TED frame. These features deliver predictable protection and coordination for critical loads in hazardous environments.
Yes, the FLB361 TT50 3 is intended for Hazardous/Classified Locations with NEC/CEC compliance. It carries area classifications compatible with Class I and II divisions and Class III, along with NEMA ratings 3, 4, 7, and 9, making it suitable for oil/gas, chemical processing, and mining environments demanding rugged protection and safety certification.
This model aligns with NEC/CEC standards and hazardous-location certifications. Certifications include UL listings for explosion-proof protection and Canada-specific certifications, with documentation accessible via the provided UL/ Eaton specification resources and installation sheets to verify compliance for your facility.
The non-interchangeable trip reduces maintenance complexity and avoids accidental cross-replacements. The threaded cover and copper-free aluminum enclosure improve sealing and corrosion resistance, lowering field maintenance needs in harsh environments. Combined with reliable thermal-magnetic protection, this model minimizes downtime and extends service life, delivering a favorable total cost of ownership for hazardous-location installations.
