Eaton Specification Sheet - OLI365FWJB-00VP
The 400A, 600V performance delivers clear value in high-current industrial installations, reducing the risk of arc-flash incidents and enabling safer maintenance operations. This three-pole fusible disconnect is designed to work with Class J fuses and is fusible without neutral, which simplifies compatibility with existing switchgear while maintaining stringent protection coordination. The NEMA 4X enclosure, constructed from 304 stainless steel, stands up to washdown, dust, and incidental exposure—extending service life in plant floors, outdoor enclosures, and harsh environments. Two voltage portals streamline wiring, allowing for cleaner terminations and quicker field assembly, especially in retrofits or OEM integrations. With UL Listed certification, compliance confidence accompanies every install, minimizing regulatory hurdles and accelerating commissioning. The unit’s dimensions and weight (50.15 in L, 21.3 in W, 9.24 in H; 100 lb) support stable mounting on standard frames and facilitate transport and positioning during installation. Compatibility with a wide range of Cu/Al conductor sizes (e.g., (2)#1/0-(2)300 kcmil; or (1)#1/0-(1)750 kcmil) helps reduce spare parts and stock requirements, delivering measurable total cost of ownership benefits.

FAQs
The OLI365FWJB-00VP is a three-pole, three-wire disconnect rated for 400A at 600V, designed for integration with common panel layouts and busway configurations. Its fusible-without-neutral arrangement simplifies retrofits and minimizes wiring disruptions, while UL Listing provides assurance of adherence to safety and performance standards. When planning, verify conductor sizes (up to 300 kcmil copper/aluminum) and ensure available mounting space matches the unit’s 50.15 in length, 21.3 in width, and 9.24 in height for a clean, compliant installation.
Plan for a sturdy mounting surface capable of supporting the 100 lb enclosure. Allocate space for wiring through two voltage portals and route conductors per the 2/0–300 kcmil or 1/0–750 kcmil Cu/Al ranges described. Maintain ventilation and appropriate clearance for NEMA 4X enclosure requirements, especially in dusty or washdown-prone environments. Ensure alignment with 600 V system controls and verify fuse compatibility with Class J fusible elements.
This switch is UL Listed, confirming compliance with safety and performance standards. It features a NEMA 4X enclosure, built from 304 stainless steel, providing excellent resistance to corrosion, moisture, and particulate ingress. The combination of UL Listing, rugged enclosure, and fusible Class J protection supports reliable operation in demanding industrial environments and simplifies regulatory audits for facilities subject to electrical safety requirements.
Ideal for OEM line isolation in manufacturing plants, assembly lines, and electrical rooms, the OLI365FWJB-00VP supports critical isolation during maintenance and startup sequences. Its 400A, 600V rating enables use with medium- to high-power feeders, while the two voltage portals and three-pole design simplify wiring and protection coordination in new installations or retrofit projects. The product’s rugged enclosure ensures durability in washdown areas and other challenging settings.
By providing a robust, UL Listed isolation solution with a durable NEMA 4X enclosure, the OLI365FWJB-00VP reduces unplanned downtime and maintenance exposure, improving overall equipment availability. The Class J fuse provision and fusible-without-neutral design simplify spares management and fuse-left-right coordination, lowering replacement costs and downtime during fuse changes. This translates to faster commissioning, safer procedures, and a lower total cost of ownership for industrial facilities.
