TMOV temperature fuse varistor is a type of varistor with over temperature cut-off functions. A temperature fuse is connected with MOV in series. When the operating current increasing continuously or MOV failure, the temperature fuse will be cut-off because it's over the limit. It makes the current to MOV cut-off, and the temperature of MOV would not increase further, thereby prevent from fires caused by MOV failure. It adopts standard leads as outlet terminals. very suitable to be installed on PCBs. TMOV zinc oxide varistor can be widely used in computer switching power supply, Power socket, UPS, telecommunication, network, railway, etc..
