AgZnO
Characteristics
AgZnO is an environment-friendly material, has the characteristics of short arcing time, high opening ability and strong capability against large current impact. AgZnO contact material has higher thermostability than AgSnO2. Comparing to AgCdO, AgZnO material has better welding resistance, and has better arc erosion resistance under breaking current of 3000 ~ 5000 A.
