Siemens HF322N Fusible Safety Disconnect Switch

Siemens HF322N is a 60 A, three-pole, four-wire fusible safety disconnect with a NEMA 1 indoor enclosure designed to safely isolate 3‑phase motors and other line loads. It is rated for 240 VAC and 250 VDC, uses three Class H/R time‑delay fuses, and provides a solid neutral (4‑wire) connection. This VBII heavy‑duty switch fits a footprint of 11.53 in W x 10.17 in D x 17.46 in H, is UL 98 listed, and offers 7.5 HP at 240 VAC 3‑phase as standard with up to 15 HP when time‑delay fuses are used. Ideal for motor control panels and indoor service entrance equipment, this HF322N is built for robust, code‑compliant isolation of 3‑phase loads.
