摘要

The fuse insert has a housing (2) with two especially insulating end cover plates (4,5), two contact blades (7,8) connected by a melting fuse conductor and an indicator (9) near the first cover plate with an interacting melting lead passing through openings in both cover plates and fixed to the second cover plate by a closure cap (19) making an electrical connection between the indicator melting lead and the contact blade. A region of a flange (16) with a contact opening has a section protruding into an opening in a cover plate (5).
