Application

-TKU1 Surge Protection Device(referred as SPD)protection against surge current resulted from direct or indirect lightning strike or similar surge voltage.SPD is applicable to circuit with rated voltage up to 400V~,rated frequency 50/60Hz.
-The SPD, using metal oxide varistor,  designed to protect both phase and neutral ine is of high electricity resistance under normal operations. In case of surge current or voltage caused by lightning strike or similar, SPD functions quickly to conduct the surge voltage /current to earth and thus effectively prevent the downstream equipments of its protected line from destruction.
-The SPD resume its high electricity resistance to secure normal operation of the protected power network without presence of the surge voltage.
