A Detailed Guide To Know What Is A Contactor

When handling lighting applications, the contactor is a common word people most often come across. By 2030, the contactors market size is estimated to reach USD 0.52 billion with a CAGR of 6.30% from 2022 to 2030. Acquiring contactors from a reliable contactor manufacturer is beneficial for businesses. 

But, what is a contactor exactly? How does a contactor work? All these topics will be discussed in this guide. 

What Is a Contactor?

Contactors are utilized with transformers and in complex machine control and several other applications. Read on to know more about the definition and purpose of a contactor in this chapter. 

Definition Of A Contactor

In simple terms, a contactor is an electrically regulated switching device that is utilized for changing electrically. They are capable of carrying large currents and turning off the contact when the coil pumps up. 

The coil or electromagnet, contacts, and enclosure are three vital parts of an electric contactor. In addition, there are various kinds of contactor devices, including magnetic contactors, knife blade switches, manual controllers, etc. 

Purpose Of A Contactor

The main purpose of a contactor is to break in or designate connections in an electrical circuit frequently under various situations. For high-voltage switching applications, contactors are generally utilized. 

What does a contactor do? When power loads have to be switched on or off quickly or very often, the contactors will be utilized. In addition to that, they are configured to turn on a circuit or cut the power supply to a circuit when switched on. How do contactors work will be explained below. 

How Does an Electrical Contactor Work?

Wondering how does an electrical contactor work? A magnetic field is usually generated when current goes through the electromagnet, and it draws the contactor’s moving core. When the metal core passes into the coil, the electromagnet coil pulls additional current till its inductance boosts. 

The moving core of the contactor pushes the moving contact, and the fixed contacts and moving contacts are held together by the force generated by the electromagnet. The circuit between the moving and fixed contacts is completed by an NC contact. 

Then the current reaches the load after going through these contacts. The magnetic force will decline when the coil becomes de-energized if the current is extracted. In addition, the magnetic force will turn to zero when the current is fully extracted and the coil becomes de-energized. 

After the coil is de-energized, the electromagnet core is moved back to its original position, and contacts are opened by the spring or gravity. The immediate on/off action of the contactors depends on their design. This chapter sums up how does a contactor work. 

What Fields Are Electrical Contactors Applied In?

The application range of electrical contactors is relatively wide as the contactors are used in a variety of different fields such as solar energy systems, lighting systems, heating and cooling systems, and many more. 

Lighting Systems

In order to deliver prominent control of huge lighting systems installations like retail stores or commercial buildings, contactors are frequently utilized. 

They are usually organized in a latching format to lessen the all-around consumption of power. Contactors make it possible to regulate numerous lighting circuits at the same time so that it is easy to control and automate lighting systems. 

Heating And Cooling Systems

Coming to the heating and cooling systems like pipes, compressors, and fans, the contactors are utilized to regulate the working of the motors of the appliances. 

To handle the high-current loads of several heating and cooling systems, such as air conditioners, electrical contactors are employed. 

Solar Energy Systems

In order to regulate the electricity flow and manage different parts, contactors are used in various solar energy systems. To detach PV arrays from the solar inverter and the grid, they are used. 

To alternate between the battery bank and solar array in solar systems with battery storage, contactors are used. Solar energy systems usually come with contactors as part of safety mechanisms. 

In case of fault situations, they can quickly detach sections and reduce the chances of electrical hazards.
