FAQs
For panel installation, verify panel bus capacity supports 60A and ensure 240 V supply with neutral is wired to the two-pole fusible switch. Mount the unit in a suitable NEMA 4X-rated enclosure area, allow clearance for 20 in depth and 9.5 in width, and follow standard safety procedures during wiring to maintain UL compliance.
The DH222NWK provides a 60A amperage rating, 240V voltage rating, two-pole configuration with neutral, 3 wires total, and uses Class H fuse protection. It carries UL Listed certification and supports 3-phase HP ratings as per catalog notes, with grounded B-phase ratings for accurate sizing in 3-phase systems.
Yes. The enclosure is NEMA 4X rated and the enclosure material is 316 stainless steel, offering excellent corrosion resistance in washdown and chemical handling areas. This makes it well-suited for food processing, water treatment, and process industries where exposure to moisture and contaminants is common.
The product is UL Listed, indicating compliance with recognized safety standards for electrical equipment. The NEMA 4X enclosure rating provides environmental protection, and the 316 stainless steel construction further supports durability in harsh environments. Catalog notes confirm grounded B-phase HP ratings for 3-phase configurations.
Expect reduced maintenance through corrosion resistance and durable stainless enclosure, lowering replacement frequency in aggressive environments. The solid protection, UL listing, and robust construction translate to fewer unplanned outages, faster fault isolation, and a lower total cost of ownership over the switch’s lifecycle in industrial facilities.
