Industrial HF221N HD Fusible Safety Switch 30A 240VAC NEMA 1

Siemens HF221N HD Fusible Safety Switch is a heavy‑duty indoor disconnect rated for 30 A at 240 V AC, designed as a 2‑pole, 3‑wire fusible safety switch for single‑phase circuits. Housed in a galvanized steel NEMA 1 enclosure, it provides a robust isolation point for motor controls, conveyors, pumps and other equipment in industrial environments where an indoor, code‑conform disconnect is required. With a 240 V, 1‑phase rating and a nominal horsepower rating of up to 7.5 hp, this HF221N is suited for mid‑size industrial loads and control panels. The device accepts Class R style fuses and is compatible with the HF221N family fuse bases, enabling straightforward field maintenance and fuse replacement without compromising enclosure integrity. As a fusible switch, it offers a clear shutoff path and compliance for safety interlocks and routine servicing within an electrical room or equipment cabinet, delivering reliable protection while occupying a compact footprint suitable for standard industrial spaces.
