Square D D322N 60A 240V AC 3-Phase Fusible Indoor Safety Switch

The Square D D322N is a new, general-duty fusible safety switch rated 60 A at 240 V AC (50/60 Hz), three-phase, in a NEMA/UL Type 1 indoor galvanized-steel enclosure — confirmed directly from the box label and interior data plate. The D322N part number decodes as follows: D = General Duty series, 3 = three-pole, 2 = 240 V AC voltage class, 2 = 60 A ampere rating, N = non-fusible designation is NOT applicable here — the "N" suffix on Square D D-series switches denotes a neutral lug included (switch IS fusible, Class H or K fuses, not included). The spring-driven Quick-Make/Quick-Break mechanism moves the blades on and off at a uniform speed independent of handle speed, and the fully insulated blade carrier prevents accidental contact with live parts. Terminals accept both aluminum and copper conductors, and padlockable provisions allow up to three locks for LOTO compliance. UL Listed; compatible with Class H or RK fuses up to 60 A; suitable for disconnecting motors, HVAC equipment, and general load-center applications per NEC Article 430.
