Eaton OLI365FWJA-0000 Line Isolation Switch - UL Listed
Part Number: OLI365FWJA-0000
Quick Summary
Eaton OLI365FWJA-0000 Line Isolation Switch protects industrial feeders in demanding facilities. Engineers often struggle with space, corrosion, and downtime when sizing large disconnects, and this unit helps streamline installation. UL Listed certification and a NEMA 4X enclosure protect against moisture and corrosion, while 304 stainless steel enhances durability in washdown areas. The 600 V rating supports safe, code-compliant operation, and a 400 A capacity provides scalable protection for growing lines. This combination reduces maintenance, minimizes spare-part needs, and lowers total cost of ownership for factories and data-center feeders.

Eaton Specification Sheet - OLI365FWJA-0000
400 A amperage rating and a 600 V operating voltage enable this switch to serve as a primary disconnect for large feeders. This consolidation reduces panel count and simplifies compliance documentation, driving installation efficiency and safer switching operations. Ideal for service entrances and main distribution paths in manufacturing plants and process facilities. 304 stainless steel construction with a NEMA 4X enclosure delivers superior corrosion resistance and washdown protection. The result is lower maintenance costs and longer asset life in harsh environments such as chemical plants and outdoor installations. This packaging also eases compliance with industry standards during inspection cycles. Three-pole, three-wire design and fusible without neutral offer straightforward wiring and fuse protection with Class J fuses, simplifying field wiring and expanding conductor sizing options up to two #1/0 to 300 kcmil. Enclosure dimensions and weight provide a clear footprint for planning and installation in retrofit or new builds; at 50.15 in length, 21.3 in width, 9.24 in height and 100 lb, it fits into standard utility spaces. Large format protection switches like this integrate with Eaton's OEM interfaces and standard mounting, improving compatibility and install speed. Industry insights: UL Listing assures compliance with third-party testing, while Class J fuse compatibility reduces downtime and maintenance risk, and the 600 V rating supports safe operation across typical industrial circuits.
