CNR thermally cut-off varistors T series and F series are thermal protective MOVs designed according to the standardof UL1449.
They comprise varistors and combustion-proof devices which will cut off the power when they are overheated in the circumstance of over-voltage limited current listed in UL1449.
CNR thermal cut-off varistors T series and F series, for the proximity of the combustion-proof device and the body of MOV, can realize the thermal cut-off function.
Comparing with most thermal fuse and MOV assembles, this production has much lower inductance, so it is better in clamping of rapid over-voltage change.
CNR thermal cut-off varistors T series and F series are be able to wave soldered, this may decrease the charge and repeated labor related to hand soldering process and simplify the production’s assembling process.
CNR thermal cut-off varistors T series are different from F series, the former is furnished with a central second lead wire, whose function is to indicate MOV’s disconnection from the circuit in order to monitor whether the circuit is connected.

FEATURES
