AC contactor is widely used as a power break and control circuit. It uses the main contact to open and close the circuit, with auxiliary contacts to control the implementation of instructions. The main contact is generally only normally open contacts, and auxiliary contacts often have two pairs of normally open and normally closed contact, small contactor is often used as an intermediate relay with the main circuit. AC contactor contacts made of silver tungsten alloy, with good conductivity and high temperature ablation
