Contactors (Solid State) are electrical switching devices that control the supply of power between two poles. They are usually used in the operation of heavy machinery, and are available in a wide range of applications and settings. Conventional contactors are generally reliable and robust, however, with the advent of modern technologies, contactors can now be combined with advanced electronics to enable a range of new applications.

2297387 application fields and working principles of contactors (Solid State) are based upon the principle of magnetically induced currents. This is a process that occurs when a magnetic field is generated around a coil, causing electrons within the coil to become charged. The motion of these charged electrons, known as eddy currents, generates a magnetic field in an opposite direction to the original magnetic field. This magnetic field directs the current to either an open or closed contact, thereby controlling the electrical power.

The use of solid state contactors for the control of electrical power is particularly beneficial due to their high switching speed and low power consumption. Some of the most common applications of these contactors include motor control, spot welding and industrial process control. When used in motor control, the contactors provide precise control over the speed and direction of the motor, allowing for efficient operation and energy conservation. In spot welding, the contactors are used to control the welding arc and ensure uniform welds, while in process control, they are used to regulate the power needed to run the flows, temperatures and pressure in a process.

In the industrial world, contactors are also used for overload protection. When a current exceeds the set maximum safe value for a certain application, the contactors will interrupt the power flow, preventing equipment from overheating and protecting the operators from shock. Contactors can also be used to protect machines from overloading and short circuits. Additionally, solid state contactors have the advantage of allowing multiple circuits to be switched on and off simultaneously, reducing the need for manual control.

Contactors (Solid State) are becoming increasingly popular, due to their high efficiency and low cost. Their durability and reliability make them a longterm investment in any business. When properly applied, they can greatly improve the performance of machines and processes, resulting in increased productivity and reduced operational costs.
