FAQs
Plan for a three-pole, three-wire setup with fusible without neutral, rated to 1200 A and 600 V. Ensure a secure enclosure mount in a NEMA 4X environment and allocate space for the 27.18 in depth, 43.11 in height, and 91.02 in width footprint plus a 575 lb unit weight. Include line and load-side indicators for quick status checks.
Class L fuses provide slow-blow protection with extended time to clear faults, enabling better coordination with downstream devices. This reduces nuisance tripping and helps protect motor windings and drives, while still delivering rapid isolation when a fault occurs in a large 3PH system.
Yes. The product uses a NEMA 4X enclosure made of 304 stainless steel, designed for washdown readiness and corrosion resistance in challenging environments found in food processing, chemical plants, and outdoor installations.
UL Listed indicates the product has been tested and meets recognized safety standards for electrical equipment. For this switch, UL Listing supports compliance with electrical codes, enhances reliability, and provides assurance for industrial applications where safety and performance are critical.
Benefit from a large, easily visible line/load voltage indicator, a robust stainless enclosure, and a documented warranty (one year from installation or 18 months from shipment). The design reduces downtime through clear status indicators and durable construction suitable for frequent maintenance in harsh environments.
