According to UL1449 3rd standard 39.4.1 Four previously untested representative devices of the SPD for each combination of conductor pairs that were tested in accordance with Section 37, are to be connected to an ac power supply having an open circuit voltage equal to the test voltage specified in Table 39.1. The power supply is to incorporate a series variable resistor that can be adjusted to obtain the short-circuit current (Isc) specified below. The variable resistor is to be adjusted such that Isc equals the values specified in Table 39.6. The four representative devices are to be energized for 7 hours, or until current to, or temperature within the SPD attain equilibrium, until the SPD becomes

Thermally protected MOVs (TMOV) 热保护型压敏电阻
Introduction of Thermally Protected MOV 热保护压敏电阻介绍
SET® The rmally protected M OV (Abbreviated TMOV) is a new patent technology in the field of surge protection. The TMOV is a fail-safe device, which integrated a disk varistor and a thermal fuse in a single package. The thermal fuse is designed to disconnect the MOV from the circuit, in case of MOV’s failure. Because the MOVs might thermally run away due to the increasing leakage current, or burn and burst in the event of a shortcircuit fault. The TMOV can offer faster response owing to its good thermo-coupling with the physical body of the MOV, comply with UL1449 3rd, IEC61643-331, IEC61051-2, GB18802.1 and ROHS compliant. The TMOV can substitute the standard MOV and provide enhanced security, never fire or burn, suitable for type 2 SPDs, Type 3 SPDs, AC Power supplies, Solar control panel and etc. SET® TMOV series have two versions: one has three lead wires with indication of MOV’s failure, another has five lead wires with indication and isolated remote signal. Both versions are ROHS compliant and wave solderable.
