AgC button contact powder metallurgy contacts used for miniature circuit breaker and protective switches
1. product name:
AgC button contact powder metallurgy contacts used for miniature circuit breaker and protective switches
2. Main Materials:
AgC
3. General Description
AgC contact materials shows a very high resistance against contact welding and low contact resistance. Resistance against welding increases with increasing graphite content. AgC materials have self-lubricating behavior when used as sliding contacts.
4. application scope
Mainly used in protective switches such as MCBs,MCCBs, residual current protective switches, or motor protective switches. Application is normally in asymmetric match with AgNi, AgW, AgWC or Cu.

7. Relevant Series 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) AgW series
All kinds of omnipotence breakers, plastic breakers, heavy charge AC/DC contactorother switches.
B) AgWCAgWCC series
Mainly used in high electricity charge switchgear such as breaker, creepage switch. Generally they are used with AgNi ,AgWC together.
