A Drop-out Fuse Should Be Replaced Immediately If It Blows.

During routine power distribution line maintenance, if a fuse drop out fuse has blown, it should not be temporarily left unattended or repaired. Instead, it should be replaced with a new fuse of the same specification as soon as possible. This is because a blown fuse has lost its overload and short-circuit protection function. Continuing to supply power may cause circuit protection failure, affecting the stability of the power supply system. Original manufacturer information indicates that after the fuse blows, the fuse tube will automatically detach from the bracket, clearly marking the faulty phase for easy location by maintenance personnel.

New ht drop out fuse fuses must be strictly matched to the rated current and voltage specifications, and copper wire, aluminum wire, or other substitutes cannot be used to replace standard fuses. Using improper materials or mismatched fuses may result in failure to disconnect correctly under increased load or short circuit, increasing the risk of equipment damage and safety hazards. Blown fuses must not be reused.
