Siemens HF221S Safety Switch Disconnect

HF221S Safety Switch Disconnect is a two-pole, fusible safety switch rated for 240 VAC at 30 A in a 1‑phase, 2‑wire configuration. Housed in a 304 stainless steel enclosure that meets Type 4/4X (NEMA 4X) requirements and IP66 sealing, it is designed for indoor or outdoor use in harsh environments. This fusible switch accepts Class R fuse clips and features a 2‑fuse arrangement with a horsepower rating of up to 7.5 hp at 240 V, making it suitable for motor disconnects of pumps, conveyors, and other industrial equipment where reliable energy isolation is essential. The rugged VBII‑series construction and corrosion‑resistant enclosure provide durable service in demanding installations, while the enclosure’s NEMA 4X/IP66 protection assists in maintaining safe operation in wet or dusty conditions. Typical applications include outdoor or harsh‑environment motor control where a code‑compliant, readily operable disconnect is required to safely isolate power for servicing or maintenance.
