Siemens HF366NA is a fusible disconnect switch designed for providing visible isolation and overcurrent protection in three-phase industrial power distribution systems. It is rated for 600A at 600V AC and features a 200kA interrupting capacity at 600V for robust short-circuit protection. The switch is constructed within a NEMA 1 enclosure measuring 6.693" x 22.047" x 45.276" and weighing 99.803 lb, and it operates reliably across a temperature range of -25°C to 70°C (-13°F to 158°F). As part of the VBII Series, this UL-listed device is engineered for compliance with industrial safety standards, making it suitable for service entrance, motor control centers, and main feeder disconnects where a fusible, three-pole configuration is required.
