DC contactors are widely used in various industrial applications for the remote control and frequent switching of DC circuits, especially for starting, stopping, reversing, and braking DC motors. Although they may not be as common as AC contactors, DC contactors have unique advantages and play a crucial role in low-voltage electrical systems globally.
This model combines stamping technology with contact components, making it ideal for use in a variety of electrical devices. The design integrates automatic spot welding and riveting between the contacts and copper alloys or pure copper, ensuring high durability and reliability.
The materials used include silver-nickel, silver-copper oxide, fine crystal silver, silver-cadmium oxide, and silver-tin oxide, among others. These materials are selected for their excellent conductivity, thermal resistance, and anti-welding properties, which are essential for maintaining stable performance under heavy-duty conditions.
DC contactors find applications in contactors, small switches, starters, and thermostats. Their performance is critical in ensuring long service life, minimal wear, and efficient operation. Key requirements for contact materials include:
1. High electrical and thermal conductivity to minimize heat loss and surface oxidation.
2. High melting and boiling points to reduce arc and spark damage.
3. Chemical stability to resist environmental degradation.
4. Appropriate hardness and elasticity to avoid excessive mechanical wear.
5. Easy to process and weld, with cost-effectiveness in mind.
For strong current contacts, the material must have low contact resistance, high anti-welding capability, and fast arc extinction. For weak current contacts, low and stable contact resistance and minimal electric wear are more important. Additionally, under DC conditions, the transfer of material between contacts should be minimized to ensure reliable operation.
Our products are certified by SGS and ISO9001, guaranteeing quality and compliance with international standards. They are widely used in switches, relays, circuit breakers, contactors, controllers, timers, and other low-voltage electrical equipment, as well as household appliances.
