Square D H365 - Fusible Safety Switch 400A 600V (200kA AIC, NEMA 1)

Square D H365 is a heavy-duty fusible safety switch designed for reliable circuit protection and isolation in industrial power distribution systems. This 400A rated disconnect switch operates at 600V AC with a 200kA interrupting capacity, providing robust short-circuit protection through Class R fuses. The NEMA 1 enclosed unit features a three-pole single configuration housed in a substantial 27.63" x 10.13" x 50.25" steel enclosure weighing 76.2 lb, engineered for demanding industrial environments. UL listed certification ensures compliance with rigorous safety standards, while the design accommodates copper or aluminum conductors from AWG 1/0 to 750 kcmil. Typical applications include motor control centers, industrial machinery, and main service disconnects where visible circuit isolation and fuse protection are required.
