TFMOV is a combination of varistors (MOV) and thermal protection component. Since varistor has the characteristics of aging or degrading; TFMOV can separate the varistor from the main circuitry by opening the thermal protection component when the varistor (MOV) degrades or fails. It is often used in which requires high reliability and weather withstanding, such as photovoltaic inverters, communication equipment, and power supplies in data centers, etc.

Thermally Protected Varistors - Mechanically Off Type Thermally Protected Varistors (TFMOV) are thermally protected varistors. TFMOVs have all the characteristics of a thermally protected varistor (MOV), but are also thermally protected. there are two types of deterioration of MOVs: natural deterioration due to long term operation, and deterioration due to an abnormal surge. When a surge occurs, the leakage current of the degraded MOV increases continuously, causing the surface temperature of the MOV to rise continuously and the possibility of fire. At this time, the heat of the MOV in TFMOV is conducted to the cryogenic alloy solder joint, which senses the abnormal temperature and acts (fuses), driving the spring slider to cut off the circuit, disconnecting the MOV from the main circuit and thus protecting the entire circuit, as well as the MOV itself will not continue to heat up, and the phenomenon of catching fire.
