company news about Why is the rated current of the fuse equal to or greater than the current in the circuit

The normal working current of the circuit is 6A. If the fuse is also 6A, the fuse will blow. If your fuse is 10A, it is no problem to connect to the normal working circuit, but if there is any fault in the circuit (such as a short circuit), the current will exceed 6A. If it reaches 10A The fuse will blow, so the fuse is to protect the circuit.
