Panasonic's ERZ-VxxD Radial Leaded Disc Type Metal Oxide Varistors "MOV" (Zinc Oxide Nonlinear Resistors - "ZNR") protect against lightning and other types of voltage surges. The Metal Oxide Varistor voltages range from 18V to 1800V and have Safety Agency recognition from 82V and higher. These devices provide large surge current capabilities in nominal diameters ranging from 5mm to 20mm.
For Varistor Voltages of 200V to 1100V, kindly also consider smaller E Series devices with better performance for their size.
