The DU322’s three-pole design ensures all three hot conductors disconnect simultaneously, reducing the risk of partial energization and simplifying lockout\/tagout procedures. The NEMA 1 indoor enclosure keeps dust and incidental contact at bay in dry indoor settings, helping you maintain performance over the long term.\u003c\/p\u003e \u003ch3\u003eFusible vs Non-Fusible — choosing the right configuration\u003c\/h3\u003e\n\u003cp\u003eUse the fusible version when you want integrated overcurrent protection in a single unit, aligning protection coordination with upstream fuses or breakers. If you already have a separate protection scheme or require a pure disconnect, the non-fusible configuration provides a straightforward, code-compliant isolation switch. Either way, the DU322 anchors your safety strategy with a proven, field-proven design.\u003c\/p\u003e \u003ch3\u003eWho benefits from the DU322\u003c\/h3\u003e\n\u003cp\u003eGreat for maintenance teams, panel builders, and warehouse floor technicians who need a dependable, stock-ready part that matches the original BOM. It’s ideal for replacing failing switches on 3-phase 240 V equipment, adding a dedicated point-of-use disconnect to new or refurbished lines, and keeping critical spares on hand to minimize downtime.\u003c\/p\u003e \u003ch3\u003eSupport and compatibility\u003c\/h3\u003e\n\u003cp\u003eAmpState stocks the Square D DU322, helping you keep consistency with the original part number.
