This part is composed by one 34S varistor disc and one Temperature Protection fuse. The fuse can assure to meet the Maximum Surge Current 40kA at 8/20 us waveform. TMOV34S-182AB has the AC voltage of 1000V and DC voltage of 1450V. This is the highest voltage in this series. It is specially used in the extremely high demand on surge withstand capacity.

Imax=40kA

Thermal Protection.
