Tips
The contactor can be divided into an AC contactor and a DC contactor according to the type of the controlled current. AC contactors are widely used as breaking and control circuits for electric power. It uses the main contact to open and close the circuit, and the auxiliary contact to execute the control command. The main contacts generally have only normally open contacts, while the auxiliary contacts often have two pairs of contacts with normally open and normally closed functions. Small contactors are often used as intermediate relays in conjunction with the main circuit.
