Siemens DTNF225 is a non-fusible disconnect switch designed for providing a visible break and safe isolation in industrial power distribution circuits. It is rated for 240V AC, 400A, and features a 200kA interrupting capacity at 240V for robust short-circuit protection within its solid-state protection system. The switch is constructed as a large-format, two-pole unit with a single configuration and ferrule connections, housed in a NEMA 1 enclosure measuring 72.835" x 42.913" x 18.898" and weighing 295.618 lb. It complies with industry standards for R-class protection and is part of the Siemens VBII Series, designed for compatibility with MAP frames. Typical applications include service entrance equipment, motor control centers, and main distribution panels where reliable load breaking and circuit isolation are required.
