Eaton Specification Sheet - DD326FDKW-00V3
The 600A, three-pole configuration delivers high-current motor protection with ample headroom for demanding loads, enabling safer starts and reducing fuse-related faults on motor feeders. The UL Listed certification and NEMA 12/3R enclosure provide verified protection against dust and environmental exposure, which translates to longer service intervals and lower maintenance costs in workshops and manufacturing floors. With a voltage indicator on both the line and load sides and a window for quick visual verification, maintenance crews can confirm operable status without power disconnection, accelerating changeovers and minimizing downtime. The fusible without neutral design and Class H fuses accommodate large conductor sizes up to 750 kcmil, supporting up to 500 hp at 480/600 V, which helps panel builders meet demanding drive requirements with a compact footprint. Its painted galvanized steel enclosure and 19.31 in depth, along with a substantial 265 lb weight, reinforce rugged field performance and long-term reliability in dusty, industrial spaces. Warranty terms of one year from installation or eighteen months from shipment add a straightforward, defendable service expectation for project teams and maintenance planners.

FAQs
The unit features a three-pole, three-wire configuration with fusible protection and a line/load voltage indicator. It supports conductors up to 750 kcmil on the feed side and accepts large motor loads up to 500 hp at 480/600 V. With a NEMA 12/3R enclosure and a painted galvanized steel body, it is suitable for dusty, damp, and general industrial environments. Ideal for motor feeders in MCCs and service panels where reliable isolation and clear status indication are required.
Key specs include a 600A amperage rating, 240V voltage rating, and a maximum horsepower rating of 400–500 hp for three-phase operation at 480/600 V. The fuse configuration is fusible without neutral, using Class H fuses. The device has a three-pole, three-wire design and includes voltage indicators on both line and load sides with a display window for quick status checks.
Yes. The enclosure is rated for NEMA 12 and NEMA 3R, providing dust-tight and weather-resistant protection, making it suitable for manufacturing floors, utility rooms, and other environments where exposure to dust or light moisture is possible. The painted galvanized steel construction also enhances durability in demanding conditions.
The product is covered by Eaton’s warranty policy: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This provides a clear service window for performance issues and supports planning for preventive maintenance and spare parts provisioning.
The unit’s clear voltage indicator, rugged NEMA 12/3R enclosure, and high current capacity reduce unscheduled downtime by improving isolation verification and reliability. Its compatibility with large conductors and high HP ratings supports fewer components and simpler wiring schemes in motor feeders, lowering installation costs and long-term maintenance expenses while meeting regulatory and safety standards.
