<p>The fuse (1) has a metal strip (4) arranged in a tubular body (2) filled with sand (5). Ends (22, 24) of the tubular body are equipped with a set of contact ferrules (6) electrically connected at ends (42, 44) corresponding to a fuse-element. Cartridges (8) are electrically connected with the contact ferrules, which comprise a slit (65), where the ferrules are made of steel. The slit extends between two edges (6A, 6B) of the contact ferrules. An indicative wafer (93) closes an opening (87) in a wall of bottom (83) of the cartridges.</p> |
