        What does an AC contactor do? Why do I need an AC contactor?

        2019-9-27 8:43:49

        1. In electrical engineering, because it can quickly cut off AC and DC main circuits and devices that can be frequently connected to high-current control (up to 800A) circuits, it is often used as a control object for electric motors and can also be used as a control factory Equipment, electric heaters, working mother machines, and various electric power units and other electrical loads, contactors can not only switch on and off the circuit, but also have a low voltage release protection.


        2. Switch on and off the circuit of the consumer.


        3. The contactor has a large control capacity and is suitable for frequent operation and remote control. It is one of the important components in the automatic control system.


        4. In the industrial electrical industry, there are many types of contactors, and the working current ranges from 5A to 1000A, which is widely used.


        Why you need an AC contactor:

        1. AC contactor is widely used as the breaking and control circuit of electric power. It uses the main contact to open and close the circuit, and uses the auxiliary contact to execute control instructions.


        The main contact is usually only the normally open contact, and the auxiliary contact often has two pairs of contacts with normally open and normally closed functions. Small contactors are often used as intermediate relays to cooperate with the main circuit.


        The contacts of the AC contactor are made of silver-tungsten alloy, which has good electrical conductivity and high temperature ablation resistance.


        2. Because the contactor is an automatic switcher used to switch on or off the AC / DC main circuit or large-capacity control circuit with load, the main control object is the motor, and it is also used for other electrical loads, such as electric heaters. Welders, lighting equipment, and contactors can not only switch on and off the circuit, but also have a low voltage release protection.


        3. The contactor has a large control capacity and is suitable for frequent operation and remote control. It is one of the important components in the automatic control system.
