AgZnO are kinds of environment-protective and non-poisonous contact materaials. AgZnO materials show high arc erosion resistance, a good resistance against contact welding, short arc time, high breaking capacity and good ability of anti-impulse big current. AgZnO show better resistance against contact welding than AgCdO and more perfect arc erosion resistanceon the conditions of breaking 3000-5000A current.
AgZnO contact are mainly used in the small and medium-capacity low-voltage circuit breakers whose rated current is under 200A, such as DZ15 serial Mould Case Circuit-Breaker, DZ15L serial residual current circuit breader. AgZnO materials are also used in some large-capacity switches, such as ME universal circuit breakers.
