170M3721

170M3721 electrical specialty fuse is an economical and reliable choice for protection of circuits against overloads and short circuits, and they are widely used in electrical network, IT and telecommunications, cable television, automotive and consumer electronics.

The fuse is constructed around the high-grade, thermally cuttable sheathed metal ribbon, which is inserted into the casing and sealed with the endcaps. The endcaps are connected to the termination caps with screws. The inner core of the fuse is a fuse element consisting of a strip of high-grade, alloy-grade copper with a thermoplastic coating placed inside a heat-resistant ceramic tube. The terminal caps are mounted onto the fuse element and the casing with screws.

When the current passing the fuse exceeds the continuous working current of the fuse, the heat generated by the current will cause the fuse element to expand and deform, causing the ribbon to separate and open the circuit. The voltage and current in the circuit will decrease accordingly and the circuit will be protected against overcurrent and short-circuit.
