Heavy Duty, Fusible without neutral
316 stainless enclosure with NEMA 4X rating provides corrosion resistance for washdown and outdoor installations, delivering long service life and lower replacement costs in food & beverage, chemical processing, and water treatment environments. Business impact: enhanced reliability and reduced maintenance, enabling safer operation of motor drives and power distribution. Application: harsh industrial floors and exposed areas where hygiene and corrosion protection are critical. Feature → Business Impact → Application. 400 A amperage rating with three poles and a fusible without neutral, Class H fuse provision, offers dependable short-circuit protection and improved selective coordination. This reduces arc flash risk and equipment damage, streamlining motor control and conveyor systems in manufacturing plants. Application: large motor loads, process skids, and heavy-duty feeders. Feature → Business Impact → Application. HP rating up to 50 hp (125/50 hp for 3PH at Std, TD/250 Vdc) provides compatibility with common plant drives, minimizing the need for multiple disconnects and simplifying maintenance. Application: general purpose drives and pumps in industrial automation. Feature → Business Impact → Application. UL Listed and NEC 230.62 compliant barriers support regulatory alignment and installation safety, reducing project risk and accelerating commissioning. Application: regulated facilities and OEM panel builds. Feature → Business Impact → Application. The unit’s dimensions and weight (57.5 in L, 27.5 in W, 12.38 in H; 175 lb) help with space planning and mounting in existing switchgear, while compatibility with large conductors (up to two #1/0 and 300 kcmil or 750 kcmil Cu/Al) enables future capacity expansion. Application: panel retrofit projects and new installations requiring robust conductor sizing. Warranty coverage (one year from installation or 18 months from shipment) protects capital investments, supporting long-term operation and service planning.

FAQs
The DH325FWK316 is a three-pole, three-wire fusible safety switch designed for 240 V three-phase systems. It accepts large conductors up to (2) #1/0 with (2) 300 kcmil or (1) 750 kcmil Cu/Al, enabling flexible feeder and motor control configurations. It is suited for standard control panels, power distribution racks, and motor control centers where a fusible disconnect is required without a neutral. Ensure compliance with NEMA 4X installation guidelines when selecting mounting locations and gasketed enclosures.
Key specs include 400 A amperage rating, 240 V voltage rating, three-pole configuration with three wires, and a maximum HP rating of 50 hp (125/50 hp for 3PH @Std, TD/250 Vdc). It uses Class H fuses and is designed as a heavy-duty fusible switch with a NEMA 4X stainless enclosure, UL Listed. These specs guide protection coordination, motor load sizing, and protection accuracy for industrial power distribution.
Yes. The enclosure is 316 stainless steel with a NEMA 4X rating, offering excellent corrosion resistance for washdown and outdoor use. It is UL Listed and compliant with NEC 230.62 barrier requirements, supporting safety and regulatory adherence in regulated facilities such as food processing, water treatment, and chemical processing plants.
The product carries Eaton’s warranty: one year from the date of installation or eighteen months from shipment, whichever occurs first. Regular maintenance should focus on enclosure integrity, fuse health, and connection torque. Its corrosion-resistant construction and clear labeling help simplify inspections, while UL and NEC compliance support predictable service cycles and reduced downtime.
ROI is driven by reduced downtime, longer service life in harsh environments, and lower maintenance costs due to corrosion resistance and robust protection. The switch’s 400 A capacity with a 50 hp maximum rating at 240 V supports efficient motor control and power distribution, while its compact, 316 stainless NEMA 4X enclosure minimizes enclosure-related installation risk and accelerates commissioning on new or retrofit projects.
