FAQs
Install the three-pole disconnect in a compliant enclosure that matches NEMA 12 or NEMA 3R ratings. Connect the three wires to the appropriate lugs, verify Class J fusible compatibility, and ensure the neutral conductor remains unused for fusible-only operation. Follow Eaton installation guidelines and local electrical codes to achieve proper clearance, torque, and safety practices.
Yes. The switch supports Cu and Al conductors with flexibility in conductor sizing: (2) #1/0 to (2) 300 kcmil, or (1) #1/0 to (1) 750 kcmil. This enables versatile wiring configurations for high-current feeders and aligns with typical industrial panel layouts, reducing the need for conductor adapters or rewiring work.
The OLI365FDJX-0000 is UL Listed, which confirms compliance with recognized safety standards. It is supplied in a galvanised steel enclosure rated for NEMA 12 and NEMA 3R environments, providing indoor and outdoor suitability and helping protect against dust, dirt, and moisture in typical industrial settings.
Ideal for line isolation in large machine feeders, control panels, and process lines where high current and robust protection are required. Its three-pole design, Class J fusible configuration, and rugged construction make it well-suited for OEM panel assemblies and retrofit projects aiming to improve safety, uptime, and fault isolation efficiency.
This unit measures 50.15 inches in length, 21.3 inches in width, and 9.24 inches in height, with a weight of approximately 100 pounds. When planning installations, allocate space for a compact yet heavy-duty disconnect, and ensure mounting provisions accommodate the 100 lb unit along with required clearances for servicing.
