Application Summary AI generated
GB/T 27751-2011 specifies technical requirements, test methods, inspection rules, and packaging for silver-nickel-graphite (AgNiC) electrical contacts. It is applied in the manufacturing and quality control of low-voltage electrical switching devices, such as contactors, relays, and circuit breakers, where these contacts are used to ensure reliable arc resistance and reduced material transfer. The standard is primarily used by electrical component manufacturers and testing laboratories in China to verify performance and consistency of AgNiC contacts in industrial and commercial power distribution systems.
