The Earldom SC04 Power Socket Easily Manages a Situation Varistor of zinc oxide (MOV) The remaining voltage value is kept within a safe range by fast blocking high voltage, which starts and absorbs 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. Hightemperature fuse protector 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.
