Product Category
Heavy Duty, Harsh Environment - EnviroLine
Enclosure and material resilience: The DH322FWKX uses an EnviroLine stainless enclosure rated NEMA 4X. The corrosion-resistant construction minimizes maintenance cycles and extends service life in washdown, coastal, and chemical-processing environments. This makes it well suited for harsh plants where splash zones, high humidity, or corrosive atmospheres challenge older switches, reducing total cost of ownership. Fuse class provision and configuration: Class H fuse protection with fusible without neutral, configured as a three-pole safety switch. This delivers selective protection and fast disconnection, reducing arc flash exposure and equipment damage. It is particularly effective for motor loads and circuits requiring reliable protection in demanding environments. Electrical ratings and horsepower: The switch supports a 60 A rating at 240 V with a maximum of 3 HP (1-phase) or 7.5/15 HP (3-phase, Std/TD). Wiring uses #14-2 Cu/Al, aligning with standard low-voltage distribution practices and simplifying upgrades for evolving motor control needs. This combination delivers predictable performance for common industrial drive applications. Wiring, compatibility, and installation: Three-pole, three-wire configuration with a compact footprint (10.22 in depth, 19.08 in height, 7.73 in width) and a 21 lb weight makes installation straightforward in standard electrical rooms or control panels. The enclosure accepts standard conductors, supporting quick integration with existing wiring schemes while maintaining robust mechanical protection. Certifications and warranty: UL Listed certification confirms compliance with recognized safety standards, while the one-year warranty (or 18 months from shipment) provides budgetary certainty and traceable support throughout the product lifecycle. These factors contribute to a clear ROI by reducing risk and simplifying procurement for facilities with strict regulatory and safety requirements.

FAQs
The DH322FWKX is a three-pole, fusible switch designed for harsh environments. It uses an EnviroLine stainless NEMA 4X enclosure and supports #14-2 Cu/Al conductors, with dimensions of 10.22 in depth, 19.08 in height, and 7.73 in width. Plan for secure wall mounting or panel integration and ensure clearance for safe operation and wiring access in washdown zones.
Class H fuses provide precise protection with defined current interrupting ratings, and the DH322FWKX offers fusible without neutral configuration. This helps prevent nuisance tripping while delivering rapid disconnection during faults, reducing motor burnout and electrical noise in demanding plants. The three-pole design ensures coordinated protection for three-wire motor circuits at 240 V.
Yes. The DH322FWKX is UL Listed and housed in a NEMA 4X EnviroLine stainless enclosure, which delivers corrosion resistance and washdown suitability. This combination provides validated safety compliance and long-term reliability in environments with moisture, chemicals, or sanitizing processes.
The switch accepts #14-2 Cu/Al conductors and supports 60A at 240V with a max horsepower of 3 HP for 1-phase, and 7.5/15 HP for 3-phase (STD/TD). Its three-pole, three-wire configuration makes it compatible with common motor control circuits, enabling straightforward integration into existing systems and standard drive protections.
The product carries a one-year warranty from installation or 18 months from shipment. For ROI, prioritize regular fuse inspections and timely replacements to minimize unplanned downtime. The UL listing and corrosion-resistant enclosure reduce maintenance frequency and parts costs in corrosive environments, contributing to lower total cost of ownership over the switch’s life.
