Eaton OLI364FDJA-00VP Line Isolation Switch - UL Listed

With a 200 A amperage rating and 600 V capability, this switch handles demanding three‑phase feeds while maintaining safe fault isolation. The three‑pole, three‑wire configuration reduces wiring complexity and provides a clean, predictable current path for motors and drives. As a result, panel owners experience fewer nuisance trips and longer service intervals, translating into lower maintenance costs and improved equipment availability in new builds and retrofits. The Class J fusible provision and fusible without neutral design offer selective protection and straightforward fuse replacement without neutral connections. This simplifies coordination with upstream protective devices and minimizes downtime during fuse changes. In practice, engineers deploy the OLI364FDJA-00VP in main line sections of machine rooms, distribution panels, and process lines where rapid isolation is essential for safe maintenance. NEMA 12 and NEMA 3R enclosures constructed from galvanized steel deliver robust protection against dust, moisture, and corrosion. This makes the unit suitable for indoor facilities and outdoor or semi-exposed locations, reducing enclosure upgrades and ensuring compliance with environmental requirements. The voltage portal feature simplifies testing and verification during commissioning and maintenance, while copper/aluminum conductor compatibility (#6-300 kcmil) supports flexible sourcing and reduces inventory variety. Overall, the OLI364FDJA-00VP supports faster installations and consistent, repeatable performance across multiple lines. Compliant with UL standards and supported by Eaton documentation, it helps drive predictable lead times, fewer part-number errors, and smoother upgrades across facilities.
