TPS fuses bring modern power fuse design to the telecommunications industry. The TPS fuse line is the first to be specifically designed to meet the unique needs of DC Power Distribution Systems. The U.L. Recognized ratings of 170Vdc and 100,000A interrupting rating along with the fuse's current limiting capability make this fuse ideal for over current protection on existing DC Distribution Systems. A unique BLUE label is used on all TPS fuses to designate their DC capability. Includes silver-plated brass ferrules and glass melamine tube.
