The Importance Of Selecting The Right Drop-out Fuse

During the selection process of the drop out fuse fuse, it is essential to ensure that the rated voltage and rated current match the protected circuit, and that the short-circuit breaking capacity meets the verification requirements of the system's three-phase short-circuit current. If the selected voltage or current is too low, the device may not be able to quickly melt and interrupt the fault current during a fault; if the selected voltage or current is too high, it may lead to difficulty in extinguishing the arc and the fuse may not be able to perform its expected protective function.
