Z Series

1.Material

AgZn(8-10)

2.Characteristics

AgZn is kinds of environment-protection and nonpoisonous contact materials.AgZnO shows high arc erosion resistance,a good resistance against contact welding,short arc time,high breaking capacity and good ability of anti-impulse large current.AgZnO shows better resistance on the conditions of breaking 3000~5000A current.

3.Manufacturing process

Internal Oxudation-Extrusion

4.Composition Control Process

5. Product Types

Wire/Strip/Rivet/Tip/Assembly

6. Application Fields

AgZnO is mainly used in the small and medium-capacity low-voltage circuit breakers whose rated current is under 200A,such as DZ15 serial moulded case circult-breaker,DZ15L serial residual current circult breaker.AgZnO is also used in some large-capacity switches,such as ME univer sal circuit breakers.
