Heavy Duty, Harsh Environment - EnviroLine
EnviroLine stainless enclosure with NEMA 4X protection translates to superior corrosion resistance, significantly reducing maintenance cycles and replacement costs in harsh sites. This means longer intervals between service and lower total cost of ownership. In practice, install in outdoor substations or washdown areas where enclosure integrity is critical. UL Listed and NEC 230.62 barrier compliance ensure regulatory alignment and project acceptance, speeding approvals and installer confidence in electrical rooms and safety enclosures. Amperage rating of 100 A with a three-pole, 600 V configuration provides clean, predictable interruption for motor feeders and service panels, enabling safe power distribution across manufacturing lines and process areas. Fuse class provision Class H and fusible without neutral simplify field wiring, improve selectivity, and reduce downtime during maintenance. HP rating up to 75 hp at 480/600 V broadens compatibility with a range of medium to high-power motors, while the compact 10.22 in depth and 24.95 in height support practical installations in limited spaces. The enclosure’s rugged design adds resilience for harsh environments, and lug-kit compatibility with service entrances enhances installation flexibility and long-term uptime.
