FAQs
The OLI365FDJA-00VT is a three-pole, 400A line isolation switch designed for 600V systems and compatible with Class J fuses. For installation, verify panel space for the 50.15 in length and 21.3 in width, secure mounting within a NEMA 12/3R enclosure, and connect load and line terminals per the Eaton wiring diagram. Ensure proper fuse insertion and enable the built-in load-side indicators to confirm isolation status prior to maintenance.
Key ratings include a 400A amperage rating and a 600V voltage rating. The unit is designed with Class J fusible provisions, allowing users to select the appropriate fusible elements without changing the switchgear. It is a three-pole OLI switch with UL Listed certification, suitable for primary isolation in industrial power distribution arrangements.
Yes. The enclosure supports NEMA 12 and NEMA 3R ratings, providing protection against dust, incidental moisture, and light rain or washdown conditions. This makes the OLI365FDJA-00VT appropriate for factory floors, outdoor equipment bays, and washdown areas while maintaining electrical isolation integrity.
The OLI365FDJA-00VT carries UL Listed certification, which simplifies supplier qualification and regulatory compliance for many facilities. Its rugged enclosure ratings (NEMA 12/NEMA 3R) support industrial safety and environmental protection standards. These certifications help justify procurement during audits and ensure reliable operation in demanding environments.
The switch includes load-side voltage indication and a dedicated voltage tester, enabling quick, verifiable isolation checks and reducing troubleshooting time. Its rugged enclosure and high-current capability minimize downtime during maintenance cycles, while UL listing and fuse provisions lower risk and spare-part complexity, contributing to a lower total cost of ownership over the equipment’s life cycle.
