Square D DTU363DS Safety Switch – 3 Pole – 100A – 600VAC/VDC – Double Throw – Non-Fusible – Heavy Duty – Stainless Steel

The Square D DTU363DS is a heavy-duty double-throw safety switch from Schneider Electric’s DTU Series, designed for reliable power source transfer in demanding industrial and outdoor environments. Built for 3-phase, 3-pole systems, it allows controlled switching between two power sources while maintaining high short-circuit withstand capability and operational safety.

This model is housed in a 304 stainless steel enclosure, making it suitable for corrosive or washdown environments where durability and weather resistance are critical. The surface-mounted design supports straightforward installation in industrial facilities, utilities, and commercial power systems requiring rugged switching equipment.

Its double-throw mechanism enables safe transfer between power sources, commonly used in backup power and critical load applications where uninterrupted operation is essential.
