The zinc oxide varistor (MOV) regulates the remaining voltage value within the state range and fast blocks high voltage, starting and absorbing lightning voltage instantly. In order to address the hidden issue of high current, ceramic gas discharge tubes (GDTs) can efficiently isolate strong currents, absorb excess current, and connect the current to the ground wire. Fuse protector for high temperatures Turn off the extremely high temperature completely. Fusible metal with a low melting point is used to make the lightning protector's high temperature fuse protector. It will swiftly fuse itself once the induced temperature reaches an unsafe level, protecting household appliances.
