ABSTRACT:
An electric fuse the fusible element of which is arranged off-center of the casing. The fuse casing is closed by caps through the end surfaces of which the knife blade contacts project into the casing. The spacing of the end surfaces of the caps to the axially inner ends of the blade contacts is substantially equal. Each of the axially inner ends of the blade contacts is conductively connected to the fusible element by the intermediary of a flexible metal strip having a smaller cross-section than each of the blade contacts. This imparts a relatively great flexibility to the unit including the blade contacts, the flexible metal strips and the fusible element.
