FOR Voltage Relay
Manufactured using either power metallurgy or sintering/extrusion method, Silver Tin Oxide (AgSnO2) material is commonly chosen as the replacement for AgCdO2. It is widely used for medium and high current contact relays due to its high resistance to welding, burn out and low material transfer.

Circuit Breaker
Silver Tin Oxide Indium Oxide (AgSnO2InO3) is similar to AgSnO2 material but it offers higher resistance to inrush current. Due to its high welding and burnout resistance, low material transfer and better resistance to instantaneous high input current, it is widely used for medium to high current relays, circuit breakers and contactors.
Multi-Layer Composite Welding Contact
Multi-Layer composite welding contact comprises of 3 layers to facilitate the ease of welding. The composite comprises of iron or copper nickel at the top layer, copper at the center and base area in either Silver Nickel, Fine Grain Silver Nickel, Silver Cadmium Oxide and Silver Tin Oxide.
