The Square D DTU363RB is a Series F double-throw safety switch designed for dependable power source transfer and isolation in industrial and commercial electrical systems. Manufactured by Schneider Electric under the Square D brand, it is engineered for 3-phase, 3-pole applications requiring reliable switching between two power sources such as utility and generator feeds.

This unit is built with a weather-resistant NEMA 3R enclosure, making it suitable for outdoor installations where protection against rain and environmental exposure is required. Its non-fusible design simplifies maintenance while maintaining strong interrupting capability for high-energy electrical systems.

The DTU363RB is commonly used in backup power systems and critical load applications where safe transfer switching is required without interrupting downstream equipment operation.
