Also a well dimensioned varistor may fail due to enormous overload. This will result in heating, smoke emission and / or displosion of varistor itself. Therefore we recommend to place varistors separate within a box on PCB. Furthermore a fuse should be in the varistor’s current path to avoid secondary current in case the varistor fails. This fuse can protect against secondaty currents and therewith caused damages. PAGE 3 OF 5
