Description

The Littelfuse Industrial TMOV34S

protected varistor represents a new development in

circuit protection. It consists of a 34mm square format

varistor element (MOV) with an integral thermally activated

element designed to open in the event of overheating

due to abnormal overvoltage, limited current conditions

as outlined in UL1449 Feb. 1998 edition. The device has a

third lead, an indicator lead, which may be used to indicate

that the MOV has been disconnected from the circuit.

This lead facilitates connection to monitoring circuitry.The

TMOV34S

the close proximity of the integrated thermal element to

the MOV body. The integrated conﬁguration also offers

lower inductance than most discreet solutions resulting

in improved clamping performance to fast over voltage

transients.
