Eaton DH222NWK316 Fusible Safety Switch - UL Listed
Part Number: DH222NWK316
Quick Summary
Eaton DH222NWK316 heavy duty fusible safety switch provides robust protection for motor circuits in demanding industrial environments. Maintenance teams struggle with downtime, corrosion, and ambiguous blade visibility that hinder safe, quick disconnection. UL Listed certification, NEC barrier compliance, and a NEMA 4X stainless enclosure deliver durable protection in harsh washdown or outdoor settings. Designed for retrofit and new installs, it integrates with standard mounting footprints and uses a neutral-fused path for coordinated control with other safety devices. Field technicians appreciate the enhanced visible blade, quick-access terminals, and stainless enclosure that stand up to washdown, chemical exposure, and harsh environments. This translates to reduced maintenance costs, faster changeovers, and improved safety compliance across manufacturing lines.
