Eaton OLI365FDJC-00VT Line Isolation Switch - UL Listed

High-current capability: 400A rating with a three-pole configuration and 600V max supports direct isolation of large feeders in manufacturing lines. This reduces wiring complexity and minimizes switching risk during maintenance. Line-side voltage indicator and tester are built in, enabling immediate confirmation of line status before opening the circuit. This feature translates to safer operations and faster commissioning in control panels. UL Listed certification paired with a rugged NEMA 12/3R enclosure makes it suitable for indoor and selected outdoor installations while meeting stringent safety standards. The enclosure protects against dust, moisture, and incidental impacts in industrial environments. Fuse class provision Class J fusible contacts provide selective coordination with compatible fuses, improving fault clearing and minimizing arcs. Three-pole design ensures balanced switching across phases, reducing neutral problems in three-phase systems. The built-in indicator aids visible verification, facilitating lockout/tagout programs and regulatory compliance. Compatibility and installation are straightforward for engineers upgrading existing panels or designing new ones. The OLI365FDJC-00VT aligns with common three-pole, 400A line isolation switch configurations, enabling smooth retrofits and quick commissioning, with protective enclosure options for indoor or outdoor use. This reduces commissioning time, lowers wiring errors, and supports scalable architectures for growing plants. Operational reliability and maintenance considerations include a robust mechanical design and clear status indication. The built-in voltage indicator and tester provide immediate verification, while UL listing and Class J fuse provisions support long-term compliance and reduced service interruptions. Maintenance teams also benefit from straightforward diagnostics and predictable wear patterns. Industry context and value: In manufacturing and processing environments, isolating power safely is essential for OSHA compliance and productivity. Customer insights: End users report faster outages resolution and less miswiring thanks to integrated indicators and clear labeling, reducing human error during start-ups. Overall, the Eaton OLI365FDJC-00VT delivers measurable ROI through safety, uptime, and compliance efficiencies in industrial environments.
