Schneider Electric's Square D D325N general-duty fusible safety switch (disconnect) is a 400 A, 240 VAC, three‑phase device designed for indoor service in a NEMA 1 enclosure. This 3‑pole, 4‑wire (3P4W) switch includes a neutral and accepts Class R fuses; it delivers a 100 kA interrupting rating at 240 V, providing robust fault interruption for motor circuits and other 240 V loads.
