Looking for a way to switch a building circuit or piece of equipment between two power sources? A double-throw safety switch is designed for that, and the Eaton DT365UGK is a 400 amp, heavy duty version. Eaton describes these switches as a way to transfer service from a normal power source to an alternate source, or to move a load from one circuit to another.

This model is non-fused, which means the switch itself does not hold fuses. It has three poles (the separate conductors it switches), is rated for 600 volts AC and 250 volts DC, and comes in a painted steel enclosure rated NEMA 1. The DT365UGK is UL Listed.
