          AgZnO is an environment-friendly material, has the characteristics of short arcing time, high opening ability and strong capability against large current impact.  Comparing to AgCdO, AgZnO material has better welding resistance, and has better arc erosion resistance under breaking current of 3000 ~ 5000 A.  AgZnO is one of the best materials for substitution of AgCdO.
