Eaton DH365FWK316 Heavy Duty Fusible Switch - UL Listed

High-current protection with 400 A amperage and a three-pole design delivers dependable isolation for large motors and feeders. This supports up to 350 hp at 480/600 V, reducing nuisance trips and improving system uptime in conveyor lines, pumps, and processing equipment. The business impact is clear: safer de-energization during maintenance and faster recovery after faults, translating to lower maintenance costs and increased line productivity. The 316 stainless steel enclosure with NEMA 4X rating provides proven corrosion resistance in washdown and outdoor environments, extending service life and reducing enclosure replacement needs in harsh facilities like food and beverage or chemical processors. This also simplifies compliance with facility cleaning protocols and reduces risk during routine servicing. Class H fuse provision with fusible without neutral enables safe isolation and precise fault clearing, supporting selective coordination and minimized system disruption during faults. The result is improved safety margins and easier panel maintenance. Edge-ready compatibility with 3-wire systems and standard protection gear allows straightforward integration into existing plant architectures, while 600 V operation supports a wide range of industrial motors and drives. The unit’s rigid construction also helps operators avoid unplanned downtime caused by enclosure failure, while its HP rating of up to 350 hp ensures it remains a scalable solution as your plant grows. In practice, technicians appreciate the combination of rugged reliability, simple installation, and predictable protection that reduces total cost of ownership over the asset’s life.
