Schneider Electric MD3304X Motor Disconnect Switch

Schneider Electric's Square D MD3304X motor disconnect switch is a non-fusible, three‑pole device rated for 30 A that provides a safe, code-compliant means to isolate 3‑phase motors in industrial systems. It supports a range of enclosure configurations—NEMA 1, 3R, 4, 4X, and 12—making it suitable for indoor panels, outdoor installations, and harsh environments; its compact footprint also emphasizes space efficiency. The MD3304X carries maximum horsepower ratings of 7.5 HP at 230 VAC, 20 HP at 460–480 VAC, and 25 HP at 575–600 VAC, reflecting its suitability for typical motor loads across different voltages. A built-in handle interlock helps prevent cover removal while the switch is ON, enhancing safety during maintenance and operations.
