20A Industrial Power AC Contactor

Product Description

As a professional manufacturer in China, SPX Electric durable 20A Industrial Power AC Contactor is an electrical device used to control circuits, mainly used to achieve on/off control of power supply in AC circuits. Its working principle is to control the on/off of the circuit through the action of an electromagnet. It is widely used in industrial automation, mechanical equipment, lighting control and other fields.

It usually consists of an electromagnet, contacts, spring, and housing. When an electromagnetic iron is energized, the magnetic field it generates attracts the contacts and closes them, allowing the circuit to be connected afterwards; When the electromagnet loses power, the spring resets the contact and disconnects the circuit.

When the current in the control circuit flows through the electromagnet, the magnetic field generated by the electromagnet will attract the moving contact and the stationary contact to make contact, forming a closed circuit, and the current can pass through. On the contrary, when the current stops flowing, the electromagnet loses its magnetic force, the contact opens under the action of the spring, and the current is cut off.

Feature：

The customized 20A Industrial Power AC Contactor is easy to operate and responsive for those who are new to or have been in the industry for a long time
As long as used properly, it has the advantages of long service life, can withstand high currents and voltages, and is suitable for various working environments.
Communication contactors can also be used in conjunction with other control devices (such as relays, timing relays, etc. to achieve more complex control functions.

Communication contactors provide a wide range of functions in various commercial and industrial applications. Its main function is to switch high-power electrical loads by energizing and de energizing the coil. The main functions are as follows:
The high quality 20A Industrial Power AC Contactor can help control high-power lighting systems

Application：

The SPX Electric 20A Industrial Power AC Contactor is widely used in lighting system control, motor start stop control, heating equipment control, and other electrical equipment that requires remote control. They play an important role in fields such as industrial automation, transportation buildings, and electrical engineering.

How to choose an AC contactor?

When choosing an AC contactor, it is necessary to configure it reasonably according to the specific load type, current, and voltage level. Ensure that the selected contactor complies with relevant electrical standards and specifications to ensure the safe and stable operation of the system. During the installation process, the manufacturer's guidance and electrical installation specifications should be followed to ensure the correct wiring and debugging of the contactor.
