Features
Using powder metallurgy process, the sheet contacts produced by mechanical mixing powder sintering and extrusion method of silver powder and nickel powder have good thermal conductivity, low and stable contact resistance, good welding resistance and arc erosion resistance under medium and small currents, and DC conditions Strong resistance to material transfer.
Silver-nickel series contacts are mainly used in:
This product is mainly used in temperature control switches and industrial control contactors with rated current of 25-40A, usually used with AgC(3~5) or AgWC(12)C(3) chip contacts in molded case circuit breakers, railway protection switches, etc.
