Product Material

AgZnO

General Description

A high resistance against contact welding characterizes AgZnO materials.They also show a good resistance against arcerosion.Contact resistance of AgZnO tends to be higher than that of AgCdO.AgZnO can be produced by means of Atomizing-sintering-extrusion、mixing-compacting-sintering techniques as well as by internal oxidation.AgZnO materials are environment-protective materials.

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.
