    EVTD's are intended, in conjunction with appropriate enclosure design, to help facilitate TVSS module compliance to UL1449. Under extreme abnormal over-voltage conditions, some units will exhibit substantial heating, arcing and venting prior to opening. Modules should be designed to contain this possibility.
