2. Main Materials: AgZnO
3. General Description:
A high resistance against contact welding characterizes AgZnO materials, they also show a good resistance against arc erosion.contact resistance of AgZnO tends to be higher than that of AgCdO. AgCdO can be produced by means of pre-oxidation-sintering-extruding, mixing-compacting-sintering techniques as well as by internal oxidation. AgZnO materials are environment-protective materials.
4. Application Scope
Mainly used in circuit breakers, especially in universal circuit breakers. Other fields of application are motor protective switches,residual current circuit breakers and AC relays.
ring-extruding, mixing-compacting-sintering techniques as well as by internal oxidation. AgZnO materials are environment-protective materials.
