2. Main application
Inner Oxidized Electrical Contact are widely used in low voltage electrical appliance

  • AgSnO2,AgSnO2In03series : Widely used in AC Contactor (CJ20,CJ40,3TF ,ETC)Power AC Switch (>=50KW),DC Contactor ,AC DC Power Relay ,Automobile and low voltage circuit breaker.
  • AgSnO2 series: Widely used in low voltage circuit breaker with rating ,electricity within 200A(such as DZ15 series ,especially omnipotence breaker )drive socket, protective socket, AC Relay DZ5L series breaker etc. Some large capacity switches also use AgZnO materials such as ME omnipotence breaker.

3.Characteristics are as follows:

  • Inner oxidized electrical contact owns excellent consistency, tiny oxidized material particle, arc corrosion resistance and long electricity lifespan.
  • Adding nickel and thulium to AgSnO2, AgSn02In2O3, AgZn02, AgCu0, AgCd0, improves their mechanical strength, ameliorate fusion, arc corrosion resistance and abrasion.
  • make high quality contact material with the advantage of grain thin and organization uniformity

4.Packing and delivery
Inside: vacuum plastic bag
Outside: carton
According to customers' request
Delivery: within 15 days
