Schneider Electric CH321NAWK Fusible Disconnect Switch

Schneider Electric's Square D CH321NAWK is a heavy‑duty fusible disconnect switch configured as a 3‑pole power isolation device rated 30 A for 240 VAC and 250 VDC. It delivers up to 7.5 HP at 240 VAC and includes a neutral in a 3‑pole, 4‑wire arrangement. The AWK variant specifies a NEMA 12 enclosure with neutral, suitable for indoor installations where dust protection and enclosure integrity matter. As a fusible disconnect, it provides a safe, clearly defined off position for servicing and control of industrial equipment or motors, while remaining compatible with standard 30 A fuse elements. This model is part of Schneider Electric's Square D safety switch family, designed to offer dependable, code‑compliant isolation in light industrial and commercial applications.
