electric middle low viltage devices contact accessories MCB contact points


An electrical contact is an electrical circuit component found in electrical switches, relays and breakers. It is composed of two pieces of electrically conductive metal that pass electrical current or insulate when the gap between them is closed or open. The gap must be an insulating medium of air, vacuum, oil, SF6 or other electrically insulating fluid.






Main Materials for silver copper bimetal contact Rivets points:


Main face Materials: Ag, AgNi, AgSnO2, AgSnO2ln2O3, AgCdO, AgZnO,


Main middle materials: Cu, CuNi


Main base matrials: low Carbon Steel, nickel, monel

AgCdO/Cu	main composition is AgCdO; stable contact resistance.
AgNi/Cu	Cd-free, better arc erosion resistance than AgCdO, excellent anti-welding resistance under large current.
AgZnO/Cu	higher thermostability than AgCdO, good electrical erosion resistance, nontoxic, and pollution-free.
AgSnO2/Cu	most promising substitute for AgCdO material; excellent arc erosion resistance and anti-welding resistance.

Main Application:


Mainly used in various switches, relays, thermostats, circuit breakers, leakage protectors and other low & middle voltages.
