Heavy Duty, Harsh Environment - EnviroLine
Enclosure and corrosion resistance: The EnviroLine stainless enclosure with a NEMA 4X rating defends internal components against moisture, dust, and chemical exposure, extending service intervals in washdown zones, outdoor installations, and challenging facilities. The result is reduced maintenance labor and fewer unplanned shutdowns, which translates to higher line uptime and safer operator environments in industries like food & beverage, chemical processing, and metal fabrication. Fuse protection and electrical isolation: The Class H fuse provision and fusible without neutral configuration deliver precise overcurrent protection and clean isolation of motor circuits. This reduces nuisance trips, protects downstream drives, and keeps production lines running. Technically, motor hp ratings of 7.5, 10/15, and 20 hp at 480–600 V can be selected for predictable performance in packaging, conveyors, and pumps. Three-pole design and wiring flexibility: The three-pole, three-wire arrangement simplifies installation and improves fault isolation, while the #14-2 AWG Cu/Al wiring specification aligns with common field wiring practices. Service entrance use is supported with a neutral or ground lug kit, enabling a flexible interface with existing electrical rooms and metering setups, reducing engineering changes. Voltage, current, and mechanical footprint: With a 600 V rating and 30 A rating, this switch accommodates mid-range motor loads and control circuits without oversized hardware. The compact footprint (10.22 in depth, 19.08 in height, 7.73 in width) and 21 lb weight ease panel integration, enabling tighter electrical rooms and simplified retrofit projects. Compliance, certification, and lifecycle value: UL Listed status, NEC 230.62 barrier compliance, and the EnviroLine stainless enclosure align with stringent industrial codes. Catalog notes support faster commissioning and lower audit risk, while corrosion resistance reduces maintenance costs and extends asset life in harsh environments.
