SIEMENS DTFC363 VBII Enclosed, Fused, Double Throw Safety Switch 100 A, 600 V, 3 P, Steel NEMA 1

Double throw switches are intended to transfer loads from one power source to another. 3-pole double throw switches are CSA certified and both horsepower and load break rated. Switches are rated for use on systems up to 10,000A when protected with Class H. They can also be used to connect a single source of power to either of two loads. In this application it is necessary to field modify fusible switches so that the fuses are on the load side of the switching mechanism. A cover interlock is provided on all ampere ratings. The operating handle may be padlocked in the off position.
