Westinghouse FDP326R Fusible Panelboard Switch

The Westinghouse FDP326R is a 3-pole, 240V, 600A Fusible Panelboard Switch designed for panelboard mounting and high-current power isolation in industrial electrical distribution. It functions as a manual disconnect with fused circuit protection for very high-amperage three‑phase systems and is commonly installed in switchboards, panelboards, motor control centers, and manufacturing facilities needing reliable high‑current protection. Key specifications include 3 poles, 600 A current rating, 240 V voltage, 50/60 Hz operation, and a panelboard-mounted configuration, with mounting hardware included. Common replacements include Eaton FDP326R, Siemens HF366R, and Square D H366R.
