Drop-out Fuses Have A Clear Structure And Are Intuitive To Operate.

drop fuse mainly consists of an insulating support, moving and stationary contacts, and a fuse tube. drop fuse cutout is designed with the fuse and the moving and stationary contacts at both ends tightly connected, in the closed state. When a short circuit or overcurrent fault occurs, the fuse melts rapidly, generating a large amount of gas inside the fuse tube. This gas is ejected at high speed, pushing the contacts away. The fuse tube then slides down naturally under gravity, thus achieving the circuit breaker tripping.
