About Product:Zinc Oxinde varistor (MOV)Fast blocking High Voltage(instantaneously starts and absorbs lightning voltage),and controls the remaining voltage value in the safe range. | Ceramic gas discharge tube (GDT)Effective isolation of strong current can effectively absorbexcess current and connect the current to the ground wire,so as to solve the hidden trouble of high current. | High temperature fuse protectorCompletely cut off the ultra high temperature. The high temperature fuse protector of lightning protector ismade of fusible metal with low melting point. Once theinduced temperature is too high, It will fuse itself quicklyand ensure the safety of household appliances.
