The basic means of controlling electrical circuits have been the same no matter how much the technology has improved over years. Amongst them are the electric contactors, and this article talk about various types of contactors and the way they work. It let you know about the differences between contactor and relay, AC contactor and DC contactor.
A Contactor A contactor is an electromechanical switch whose major function is making or breaking the connection between the power supply and the load. The contactor is controlled electrically and compared to the switched circuit it is usually powered at a much lower level. Controlling electric motors, lighting, thermal evaporators, capacitor banks, heating, and other electrical loads are included under a contractor’s applications. Electric contactor ranges in size and capacity. You have the one that you can easily lift with your hand to massive ones measuring about a meter on the side. Magnetic Contactor It is the most advanced of them and is the latest contactor design. In industrial applications, it is commonly used due to its features like
From the external control circuit, current passes through the contactor and then excites the electromagnetic core. In turn, a magnetic field is created by the coil/electromagnet which helps the contactor in moving the armature. Between the fixed and moving contacts, a normally closed contact then makes the circuit complete. Through these contacts to the load, the current is then able to pass. When there is the removal of current, the coil becomes de-energized, and the magnetic force falls to zero. The spring force is very higher and then it pulls back the armature opening the circuit. Conclusion In the control of a circuit, contractors are indispensable devices and come with added safety features. With every electrical device, it is necessary to make sure that you find one that matches your needs and function. You also require a reliable fuji magnetic contactor supplier which gives you genuine products meeting global standards like IEC. Follow us on Facebook
