A contactor is a key element in electrical systems, responsible for controlling the flow of electricity by making or breaking electrical circuits. A contactor operates through several types of contacts that are crucial for its efficiency and durability.
Different Types of Contacts in a Contactor
Within a contactor, there are different types of contacts, including power contacts, auxiliary contacts, and contact springs. Power contacts are split into stationary and movable categories. Stationary contacts remain fixed in place, while movable contacts can shift, enabling or interrupting the flow of current. Auxiliary contacts serve a signaling role, helping to indicate whether the contactor is engaged or not.
Materials Used for Contacts in a Contactor
The materials chosen for making the contacts in a contactor are of utmost importance, as they must be able to endure high currents, mechanical stress, and erosion. For high-current and DC applications, silver tin oxide is commonly used due to its stability and welding resistance. For low-current applications, silver nickel or silver cadmium oxide provides the necessary properties for optimal performance.
