specific market applications

Power distribution systems: They are crucial components of thermal-magnetic molded-case circuit breakers and miniature circuit breakers. In residential, commercial, and industrial power distribution systems, when the current exceeds the rated value, the Dry Contactor Electrical Silver Contacts bend due to heat, triggering the circuit breaker to trip and cut off the circuit, thus protecting the safety of the power distribution system and electrical equipment.

 

Motor protection: In the industrial field, bimetallic Contactor Electrical Silver Contacts are often used to protect motors. Motors may have over-current problems during operation, and bimetallic contact-breakers can sense the current change and cut off the power in time when over-current occurs, preventing the motor from being damaged due to over-current.

 

Thermostats: Rotating Electrical Contacts are commonly used in thermostats for heating and cooling systems. Due to the different thermal expansion coefficients of the two metals, they can respond to temperature changes, control the on-off of the circuit, and achieve precise temperature regulation.

 

Automotive electrical systems: In the automotive industry, they are used in automotive relays, connectors, and switches. For example, Open Contactor Silver Contacts are commonly used in automotive relays, which can provide good arc resistance and welding resistance, ensuring the reliable operation of automotive electrical systems.

 

Welding equipment: Dry Contactor Electrical Silver Contacts are widely used in welding equipment. This kind of contact has excellent high-temperature resistance and arc erosion resistance, and can withstand the high-current and high-temperature environment during welding, ensuring the normal operation of welding equipment.

 

Aerospace field: Bimetallic contact materials are also used in some aerospace-related electrical devices. They need to have excellent performance, such as high-temperature resistance, arc resistance, and low resistance in harsh environments, to ensure the reliable operation of aerospace electrical systems.
