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.
