(Typical time to open according to UL1449 Abnormal Overvoltage
Limited Current Test.)
NOTE: Thermally Protected Varistors are intended, in conjuction
with appropriate enclosure design, to help facilitate TVSS module
compliance to UL 1449. Under extreme abnormal over-voltage
conditions, some units will exhibit substantial heating, arcing and
