1. Under Ul1449 limited current testing parts rated >420V will not open due to 600V voltage limit. Devices
2. Regarding thermal cut-offs for ratings up to 420VAC.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to
the device. This is a stress only rating and operation of the device at these or other conditions above those
indicated in the operational sections of this specification is not implied.

Description
Metal Oxide Varistors (MOVs) are rated for specific AC line
operating voltages. Exceeding these limits through the
application of a sustained abnormal over-voltage condition
could result in overheating and damage to the MOV. This
condition is specifically identified and addressed in the UL
1449 TVSS Standard – called Limited Current Abnormal
Overvoltage test.
The Littelfuse TMOV25S™ (Thermal MOV) Series
addresses this test condition in a single integrated
package. The TMOV
UltraMOV™ Series which meets the surge suppressor
component recognition requirements of UL 1449 for both
cord connected and permanently connected TVSS end
products. Additionally, the TMOV
patented integrated thermally responsive element within
the body of the device which will open-circuit the varistor
in case of overheating due to the abnormal over-voltages
per UL 1449 requirements–Note 1.
The TMOV
voltage requirements of UL 1449 (Abnormal Over-voltage
Limited Current requirements up to and including the
10A/7hrs requirement).
The TMOV
