ABSTRACT:
An electric fuse for high voltage circuit comprises an insulative tubular casing closed at both ends with metal caps and has an insulative cylindrical member within said tubular casing disposed eccentrically and is offset relative to the major axis of said tubular casing so as to define an annular space therewith which is non-uniform in width. The annular space has a wider portion on one side of said tubular member and a narrower portion on the other side thereof. A fusible element is stretched in said narrower portion of said annular space and is secured at both ends to said metal caps.
