Corrosion-resistant enclosure translates to longer service life in washdown zones, reducing maintenance costs and replacement parts. This means greater uptime for conveyors and pumps in manufacturing lines and process environments. The three-pole fusible switch with neutral enables true isolation in four-wire circuits, supporting safe motor control and simpler circuit protection strategies in food processing and packaging lines. NEMA 4X stainless steel construction offers rugged durability for outdoor or damp installations, lowering enclosure leaks and corrosion-related failures across facility floors and outdoor equipment corners. The Class H fuse provision with fusible contacts ensures dependable overcurrent protection, shielding motors from damaging surges and enabling predictable maintenance intervals. Wiring flexibility with #14-2 AWG Cu/Al simplifies field termination, reduces labor time during installation, and supports standard control-circuit integration for OEM and retrofit projects. UL Listed certification reinforces compliance and procurement confidence, smoothing spec adherence for contractors and end users alike.

FAQs
Installation requires a three-pole, four-wire configuration with a neutral conductor. Use #14-2 AWG Cu/Al conductors within the switch’s feed and load terminals, ensuring the outer enclosure remains sealed to preserve the NEMA 4X rating. Follow standard lockout/tagout procedures and verify UL Listed compliance during commissioning to ensure safe and compliant operation.
Key specs are: 30 A rating, 600 V maximum voltage, three-pole configuration with four wires, fuse class provision Class H, fusible with neutral, and a max horsepower rating of 7.5–20 hp depending on motor configuration (1/3 PH at 480–600 V). Wire size supports #14-2 AWG Cu/Al, and enclosure is NEMA 4X with 304 stainless steel.
Yes. The unit uses a 304 stainless steel enclosure rated NEMA 4X, designed for washdown and corrosive environments. This construction minimizes corrosion-related downtime, extends service life in damp or outdoor settings, and maintains enclosure integrity even in frequent cleaning cycles, which is a common requirement in food processing and manufacturing facilities.
The DH361NWK is UL Listed, which provides independent safety certification and helps with code compliance and procurement approvals. While other standards like IP/SIL/CE are industry-relevant, the UL Listing coupled with the NEMA 4X enclosure guarantees robust protection for motor-control disconnects in challenging environments.
The device offers predictable maintenance with corrosion-resistant stainless construction, reducing enclosure maintenance and spare parts costs over time. Its reliable isolation and protection minimize unplanned downtime for critical equipment like conveyors and pumps, improving overall asset availability and enabling faster maintenance turnaround during scheduled plant outages.
