Product Detail

Model No.: C-301

tri-metal composite button contact widely used in micro switches and breakers protector

tri-metal composite button contact widely used in micro switches and breakers protector

 

Specifications

tri-metal composite button contact
Baseband:Cu,Fe,CuNi...
Clad:Ag,FAg,AgNi,AgCdOaaaa
Usage:Micro switches,thermostat,keys
 

1. Product name: tri-metal composite button contact
2. Materials: AgW,AgNi,AgCdO, AgNiC,AgWC

 

3. Characteristics
A) Silver graphite contact has a good performance in resistance to contact wedding, low contact resistance and high arc erosion resistance
B) AgWC contact is very hard and sufficient mechanical strength, during arcing a protective gas layer of CO is formed which limits the reaction of oxygen on the contact surface and therefore the formation of metal oxides

4. Applications

AgW, CuW, AgWC contacts choose different powder materials with adding inside Ni, Co mineral and by using pre-sinter and active sinter technology then improve their consistency and ameliorate electrical function of contact materials. Mainly used in middle and large capacity relay, contactor, middle and small capacity low voltage breaker, DC/AC switch, drive protective switch, creepage protective switch etc.
Their applications as follows:
A) AgC series
Mainly used in protective switch such as miniature breaker, creepage protective switch or motor protective switch with coupling contact in AgW.
B) CuW series
Widely used in high voltage breaker.
C) AgWCAgWCC series
Mainly used in high electricity charge switchgear such as breaker, creepage switch. Generally they are used with AgNi ,AgWC together.
D) AgNi series
Widely used in DC/AC relay, designation switch, contactor, light switch, thermal controller, timer of washer etc.
E) AgNiC series
Widely used in omnipotence breakers such as DW45 intelligence coupling with AgW.
F) AgW series
All kinds of omnipotence breakers, plastic breakers, heavy charge AC/DC contactorother switches.
G) Silver oxidized metal series
Mainly used in wasser mengen in relay,contactor, small and medium-sized capacity and DC low voltage circuit breaker switch powder protection switch and leakage protection switch,etc.
