Schneider Electric H324N Disconnect Safety Switch

Schneider Electric's Square D H324N is a heavy-duty fusible disconnect switch rated for 200 A at 240 V, configured as a 3-pole, 4-wire (with neutral) device intended for indoor use. Housed in a NEMA 1 enclosure, this safety switch provides a dedicated isolation point to safely de-energize three‑phase feeders and connected equipment for installation, servicing, or maintenance. As part of Square D's family of heavy‑duty safety switches, the H324N is built to withstand indoor commercial environments where a robust, code‑compliant disconnect with a neutral conductor is required. The model is widely cataloged as a 240 V, 200 A three‑phase fusible disconnect, offering reliable isolation for feeders and industrial loads while keeping live components enclosed for protection. In practice, it serves as the primary disconnect near motors, pumps, conveyors, or other three‑phase equipment, enabling safe lockout/tagout procedures and compliance with electrical safety standards.
