Square D DTU363AWK Safety Switch – 3 Pole – 100A – 600VAC/VDC – Double Throw – Non-Fusible – Heavy Duty

The Square D DTU363AWK is a heavy-duty double-throw safety switch from Schneider Electric’s DTU Series, designed for reliable source transfer and isolation in demanding industrial and commercial electrical systems. Built for 3-phase, 3-pole applications, it allows safe switching between two power sources while maintaining high short-circuit withstand capability.

Engineered for durability, this unit supports both 600VAC and VDC operation and is suitable for high-energy distribution environments. Its double-throw mechanism enables transfer between power supplies without interruption to downstream systems, making it ideal for backup power configurations and critical load switching.

This switch features a rugged galvanized steel enclosure with surface mounting design and is built for long mechanical life in harsh environments. With a high interrupting rating and heavy-duty construction, it is well-suited for industrial power distribution and transfer applications.
