Schneider Electric H663AWK Fusible Disconnect

H663AWK is a heavy‑duty fusible safety switch that provides a 100 A, 6‑pole disconnect for three‑phase power, rated up to 600 V AC/DC and capable of interrupting up to 75 HP. Encased in a NEMA 12 enclosure, it is designed for reliable isolation in indoor or protected environments where dust and moisture control matter. This fusible disconnect uses a quick‑make, quick‑break operating mechanism and a dual‑cover design to improve safety during servicing, and it is engineered to have a mechanical endurance three times greater than NEMA standards. When used for service‑entrance applications, it can be equipped with a neutral assembly or an equipment grounding kit to suit grounding requirements. With six poles, this switch provides robust isolation for large motor loads such as HVAC compressors or industrial pumps, making it well‑suited for factory floors and distribution panels that require a durable, code‑compliant disconnect.
