AgSnO2 (silver tin oxide) and AgCdO (silver cadmium oxide) material performance comparison

AgSnO2 (silver tin oxide) and AgCdO (silver cadmium oxide) material performance comparison

  AgSnO2 contact material is environmentally friendly and non-toxic, with excellent resistance to welding and arc ablation. Generally speaking, under the condition of large current, AgSnO2 has better arc ablation resistance than AgCdO; under lamp or capacitive load, the contact resistance of AgSnO2 is high, but under DC lamp or click load, it performs A low and stable contact resistance; compared to AgCdO under DC conditions, AgSnO2 material has better transfer performance. AgSnO2 contact material is widely used in various large-capacity contactors, power relays, medium and small-capacity low-voltage circuit breakers and automotive electrical appliances.
