Double throw safety switches are intended to transfer loads from one power source to another. All 2 and 3-pole double throw switches are suitable for use as service equipment. All are UL Listed. Switches are rated for use on systems up to 10000 A when protected with class H fuses or 100000 A when protected with class R or class T fuses. They can also be used to connect a single source of power to either of two loads.
