TMOV
Thermal Characteristics
Note : The TMOV
in conjunction with appropriate enclosure design, to
help facilitate TVSS module compliance to UL 1449, 2nd
Edition Section 37 .4 (abnormal overvoltage limited current
requirements). Under these extreme abnormal overvoltage
conditions, some units will exhibit substantial heating,
arcing and venting prior to opening. Modules should be
designed to contain this possibility. Application testing is
strongly recommended.
