The AC contactor is widely used to break and control circuits. Its main contact is used to open and close the circuit and its auxiliary contacts are used to execute control commands. The main contact is generally normally open one while the auxiliary contacts are often two pairs of contacts with normally open and normally close functions. Small contactors are often used as the intermediate relay to support the main circuit.
The contact is made of silver tungsten alloy. It has excellent conductivity and high-temperature ablation resistance.
