Abstract (en)

[origin: JPH04322028A] PURPOSE: To simplify a structure of an electric fuse, and to enhance switching ability and reliability. CONSTITUTION: When an internal pressure of a casing 1 increases and then reaches a peak value at the time of disconnecting a fuse element 6, a pressure limiting device 8 discharges at least some of its content. This pressure limiting device 8 is provided in the casing 1 together with the fuse element 6, thereby preventing the breakage of the casing 1.
