FAQs
The DH326FGK-LS is a three-pole, 600A fusible safety switch designed for 240V three-phase power. Install it in an indoor NEMA 1 enclosure with the Neutral Kit if service-entrance use is required. Plan for a two-person lift due to its 140 lb weight, and observe labelling for UL Listed compliance. Use the manufacturer’s mounting and termination guidelines to ensure proper torque and safe operation.
Terminations support large conductors, including (1) #2 conductor to (1) 600 kcmil aluminum, and (1) #1/0 to (1) 750 kcmil aluminum, as specified. When wiring, verify lug torque values from Eaton’s datasheet and ensure clearance for high-current cables. This compatibility enables reliable connection to feeding or distribution conductors while minimizing resistance and heat.
Yes. Catalog notes indicate it is suitable for service entrance use when a Neutral Kit is installed. This enables proper neutral grounding and code-compliant service isolation, which is critical for main disconnect applications. Ensure the Neutral Kit is sourced and installed per Eaton guidelines to maintain UL Listed status and regulatory compliance.
The DH326FGK-LS carries UL Listed certification and uses a NEMA 1 enclosed painted steel enclosure. It adheres to NEC 230.62 (C) compliant barrier requirements, supporting safer service entry and installation in industrial facilities. While CE is not listed, these certifications help drive compliance in many North American electrical systems.
Eaton offers a warranty of one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on the robust NEMA 1 enclosure, Class H fuse protection, and UL Listed components to minimize unscheduled outages. Plan routine inspections, verify fuse integrity, and keep spare fuses and Neutral Kit components on hand to sustain uptime.
