ABSTRACT:
A pair of metallic electrodes gripping a fusible wire are attached to opposite ends of a box-like shaped body into which is pressed a lid portion to an extent to be slightly sunken relative to an upper surface of the body. Then adhesive is applied to the lid portion to fix the lid portion to the body to seal the interior of the body. The fusible wire is extended in the interior of the body in a floating condition. Such a construction allows easy manufacture, enables variation of pre-arcing time-current characteristic to be kept to minimum, and brings about a high degree of reliability.
