Introduction to TMOV

TMOV, or Thermally Protected Metal Oxide Varistor, is an advanced over – voltage protection device. It combines a metal oxide varistor (MOV) with a thermal disconnection mechanism. The MOV part is designed to protect electrical and electronic circuits from voltage surges by diverting excessive current, while the thermal disconnection feature helps prevent thermal runaway. When the MOV is overheated due to continuous over – voltage or aging, the thermal protection mechanism will disconnect the MOV from the circuit, thereby avoiding potential fire hazards and ensuring the safety and reliability of the protected system.
