Metal-Oxide Varistors (MOVs) ® Industrial High Energy Thermally Protected Varistors > TMOV 34S Varistor Series TMOV®34S Varistor Series RoHS Description The Littelfuse TMOV®34S thermally protected varistor series consists of a 34mm square format varistor element (MOV) with an integral thermally activated element. This element is designed to open in the event of overheating due to abnormal overvoltage, limited current conditions. Certain TMOV®34S varistor are offered with a "monitor" lead which may be connected to signalling circuity to indicate if the MOV has been disconnected from the circuit. TMOV®34S varistor series offer quick thermal response due to the close proximity of the integrated thermal element to the MOV body. The integrated configuration also offers lower inductance than most discrete solutions resulting in improved clamping performance to fast over voltage transients.

This signifies that the circuit is no longer protected from transients by the MOV. Figure 1. Application example 1 Line Application Example 3 Line Fuse In this case, the LED is normally on, and is off when the thermal element opens.
