PVR-20D391K - Pan Overseas Zinc Oxide Varistors
When high Voltage transients or surges produced by induced lightning, switching or electrical noise, the varistor will switch from the rest stage to the protective stage.
It is extremely high resistance value will change to very low and causes short circuit, allows large currents to go through.
