Abstract

An externally-controllable thermal tripping device comprising a voltage dependent resistor including a voltage dependent resistor chip; a thermal tripper including a tripping electrode; and a controllable heating element. The tripping electrode is connected to an electrode of the voltage dependent resistor chip through a meltable welding material, and the controllable heating element is controlled by an external control device to generate heat and transmit generated heat to a commissure of said welding material to melt said welding material and electrically disconnect the tripping electrode from the voltage dependent resistor chip.
