Siemens HF325NRA - Fusible Safety Switch 400A 3-Pole (NEMA 3R 240V)

Siemens HF325NRA is a heavy-duty fusible safety switch designed for reliable circuit isolation and protection in industrial power distribution systems. This 3-pole disconnect switch operates at 240V AC with a 400A current rating and features a robust NEMA 3R enclosure rated for outdoor use. Constructed with a 200kA interrupting capacity at 600V, the switch accommodates wire sizes from AWG 1/0 to 750 kcmil for both copper and aluminum conductors. Compliant with industrial safety standards, it maintains operational integrity across a temperature range of -25°C to 70°C (-13°F to 158°F). Typical applications include motor control centers, industrial machinery, and main power distribution panels where secure isolation is critical.
