Eaton DH325FDKV Heavy Duty Fusible Safety Switch - UL Listed
Part Number: DH325FDKV
Quick Summary
Eaton heavy duty fusible safety switch provides reliable fault isolation for industrial control panels and feeders. Panel downtimes and arc-flash risk slow projects; this unit reduces both with rugged construction, UL listing, and NEC-compliant barriers. It carries UL Listed certification and an NEC-compliant barrier inside a NEMA 12/3R enclosure, with Class H fuse provision, to support safe, code-compliant operation. This combination helps you protect personnel, minimize commissioning time, and simplify lifecycle maintenance, while enabling scalable power control in 400 A circuits. Designed for demanding environments, it supports large feeder conductors and provides clear visibility through Enhanced Visible Blade. That helps maintenance teams perform faster lockout/tagout and reduces service time during replacements.

FAQs
The DH325FDKV is a three-pole, three-wire device designed for use in a NEMA 12/3R enclosure with a galvanized steel enclosure. Plan for a 64.5 inch depth, 26 inch width, and 13 inch height footprint, allowing for large feeders and up to 750 kcmil Cu/Al conductors in certain configurations. Ensure compatible mounting, adequate clearance for front accessibility, and adherence to NEC 230.62 barrier requirements. UL Listed protection and Class H fuse provisions should be incorporated into the overall safety plan.
Yes, the DH325FDKV uses a Class H fuse configuration and is designed for fusible operation without a neutral. Terminal options accommodate large feeders, including configurations such as two #1/0 to two 300 kcmil or one #1/0 to one 750 kcmil copper or aluminum conductors, enabling high-current distribution in 400 A circuits for demanding applications.
The unit offers a NEMA 12 or NEMA 3R enclosure, suitable for indoor protection and sheltered outdoor or semi-outdoor environments. With painted galvanized steel, it provides durability against dust and outdoor exposure in covered areas, aligning with common industrial installation standards for reliable, long-term operation.
The switch is rated for 400 A and 240 V. Its horsepower range supports up to 50 hp standard with 125/50 hp for three-phase configurations under specific voltage and duty cycle conditions, making it suitable for mid-to-large motor and equipment protection in manufacturing lines and material handling systems.
This safety switch is UL Listed and designed to meet NEC 230.62 (C) compliant barrier requirements. The enclosure and protection features align with rugged industrial standards, and the HDSS catalog designation reflects its heavy-duty construction for demanding environments. These certifications help ensure regulatory compliance and safer, code-conforming installations.
