FAQs
Installers should plan for a top-fed, three-pole arrangement with three-wire wiring. Ensure adequate panel clearance for the 16 in length, 28 in height, and 24 in width footprint. Verify a UL Listed enclosure and appropriate NEMA rating (1, 3R, 4, 12) for the environment, and consider optional features like ground fault relay or auxiliary contacts to meet specific protection schemes.
The switch is rated for 1200A at 480V, enabling direct protection of large feeders and minimizing device stacking. Its top-feed, three-pole design reduces wiring complexity, while the charge-before-close mechanism improves switching safety and reduces inrush. This combination supports reliable operation in manufacturing lines, switchgear cabinets, and motor control centers.
Yes. The device is UL Listed and compatible with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures, enabling installation in a wide range of industrial environments. Optional features such as ground fault protection and auxiliary provisions can further enhance compliance and system safety.
Regular inspection of the fusible protection path, verification of trip and close sequencing, and checking auxiliary contacts for proper operation are recommended. If equipped, monitor ground fault relay status and blown fuse detection. Scheduling these checks during routine maintenance minimizes unexpected trips and extends switchgear life.
The product occupies a footprint of 16 inches in depth, 28 inches in height, and 24 inches in width, weighing approximately 180 pounds. Plan mounting within 480V switchgear or control panels with sufficient access for maintenance, wiring, and potential future upgrades or optional accessory installations.
