FAQs
OLI365FWJX-0000 is a three-pole, three-wire fusible switch designed for OEM line isolation. It supports conductor sizes up to (2)300 kcmil or (1)750 kcmil Cu/Al and fits standard enclosure footprints used in large distribution panels. When pairing with existing gear, verify mounting clearances, bus bar spacing, and available internal wiring space to ensure safe, code-compliant installation.
The unit provides a 400 A amperage rating and a 600 V voltage rating with Class J fusible protection. These ratings improve short-circuit response, maintain system stability during faults, and support proper fuse coordination with upstream protection. Ensure device coordination with upstream breakers for selective protection and minimal downtime during maintenance.
Industries with demanding washdowns and high-humidity environments—such as food & beverage, pharmaceutical, chemical processing, and general manufacturing—benefit from the 304 stainless steel NEMA 4X enclosure and corrosion resistance. The rugged design also suits outdoor installations and plants with stringent sanitation and safety requirements.
This Eaton line isolation switch is UL Listed and housed in a NEMA 4X enclosure. The 304 stainless steel construction provides durability in harsh environments. These certifications support compliance with many electrical safety programs and simplify procurement and system validation in regulated industries.
The solid stainless enclosure and robust wiring options reduce corrosion-related wear and field wiring issues, lowering maintenance costs over time. Heavy-duty construction and UL/NEMA ratings contribute to longer service life, minimizing downtime during routine maintenance and helping justify total cost of ownership in capital projects.
