TMOV ® 25S Varistor Series
Metal Oxide Varistors (MOVs) are rated for specific AC line
operating voltages, and exceeding these limits through the
application of a sustained abnormal over-voltage condition
could result in overheating and damage to the MOV.
The Littelfuse TMOV ® 25S (Thermal MOV) Series was
designed to address this condition in a single integrated
package.
The TMOV ® 25S Series incorporates a 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-voltage events.
The TMOV ® 25S Series is based on the Littelfuse
UltraMOV™ 25S Series, which meets the surge
suppressor component recognition requirements
of UL1449 3rd edition for both cord connected and
permanently connected SPD end products.
