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.
