Generally speaking, in electrical engineering Frost on the contact surface of the car fuse holder will cause cold flakes on the dew and armature surface, affecting the normal conduction of the contact. Therefore, it is necessary to use transients in the relay coil and limit the peak voltage to a certain range.

Usually kilovolt voltage surges and surge voltages are applied to systems of fuses and power systems to create coils in other equipment and energy. Source storage function, when the coil inserted into the fuse holder is disconnected, the stored induced electromotive force generates up to multiple discharge voltages.

Since the coils of the basic specifications of line fuses in the general sense have working voltage and critical voltage, when choosing a waterproof fuse holder, it is necessary to choose Vibration that meets technical requirements.
