Schneider Electric H321N Fusible Safety Disconnect Switch

The Schneider Electric H321N is a heavy‑duty fusible safety disconnect switch rated 30 A for a 3‑pole, 4‑wire configuration with a neutral, designed for 240 V operation (up to 7.5 HP) and intended for indoor NEMA 1 service. This fusible disconnect provides a dedicated motor disconnect path, enabling safe maintenance by isolating all live conductors while preserving fuse protection for the circuit. As part of the Square D by Schneider Electric family, the H321N is a three‑pole, four‑wire safety switch designed for general‑duty applications where a controlled disconnect is required for small to medium motor loads and equipment in commercial or light industrial settings. With its three‑phase, 240 V design and a neutral terminal, it ensures simultaneous disconnection of all conductors served by the switch, delivering reliable protection and serviceability in environments that demand code‑compliant isolation.
