The regarded part is a switching device. It is a big-size relay. The contactor is used to switch the current supplying electric motors, compressors, or other high power loads.
A 3-phase contactor is a simple and reliable device. Its task is to repeatedly turn on and off circuits and loads. Thus, it ensures a continuous and stable machine operation. In most cases, contactors function on asynchronous motors. Despite such harsh operating conditions, they are able to start millions of times due to greater electrical and mechanical durability.
The main components of the part are a coil, a core, and a group of contacts. When speaking about its fields of application, no power mechanism can run without the device. For instance, a three-phase contactor is found in lathe or milling machine, ventilation, pumping, or heating systems, etc.
Functions of the Device
- The product is able to close and open an electrical circuit several thousand times an hour. Thus, it starts and ends the operating cycle.
- The tool operates remotely. It can start and turn off machines while being far away from a working mechanism. The ability to function remotely allows using the tool in such spheres as utilities, industry, construction, transport, and even household.
- A three-pole contactor fully automates the above-mentioned processes. As a result, it simplifies the workflow of the maintenance team.
If a timely diagnosis is made, the device ensures a smooth operation. High-quality components, including wire, the core, and contracts, guarantee a long-lasting life period.
