Siemens F353H Enclosed Fusible Switch Type 12 100A 600VAC 3-Phase

Siemens F353H is a three‑pole enclosed fusible switch rated for 100 A and 600 V AC, designed to provide fused isolation for three‑phase circuits in an indoor Type 12 enclosure. As a fused disconnect, it combines switching and protection in a single assembly suitable for use in electrical distribution panels, motor control circuits, and industrial control applications where reliable isolation and fuse protection are required. The F353H aligns with Siemens' I‑T‑E legacy line and is intended for indoor installations that demand a robust, easily serviceable disconnect with a clearly labeled on/off operation. With its Type 12 enclosure rating, the unit is designed for indoor industrial environments and provides protection appropriate for moderate dust and moisture exposure while allowing straightforward maintenance access.
