Transient suppressor. It is a spark gap that will turn on and conduct when it reaches breakdown voltage, It will withstand 470V and breaks down typically at 800-900V to present almost a short circuit until the current drops to a low level ( under around 1A) and clamps the voltage to typically 30-100V.
