TDK Product Features

ThermoFuse™ varistors are housed components, which consist of a disk varistor in series with a thermally coupled fuse. If the varistor overheats, the thermal fuse activates and disconnects it from the power circuit, thus preventing the occurrence of fires. This increases reliability and protects the equipment. Both the housing and the coating of the varistors are made of flame-retardant material.
