AgCdO10 Silver Contact Tips with good arc erosion widely used in almost every type of low voltage switching devices

1. Product name: AgCdO10 Silver Contact Tips with good arc erosion widely used in almost every type of low voltage switching devices

2. Materials:AgCdO10

3. general description

AgCdo contact belong to the group of the most widely used ones on the field of low voltage electric apparatus. They combine a satisfactory resistance against contact welding with a good arc erosion resistance and a fairly low contact resistance over its complete service life. They are produced with two different techniques, pre-oxidation-sintering-extruding and internal oxidation. In both cases CdO content may range from 10 to 20wt%. However,Cd and CdO are considered to be hazardous to health and the environment. For this reason the use AgCdO materials will be banned in a number of countries.

4. application Scope

Mainly used in almost every type of low Voltage switching devices. They are typically used in microswitches, relays, light switches, contactors, switches for household appliances, some type of protective switches, as well as in certain types of circuit breakers.
