Why would you use a contactor?
Why are Contactors Used? Contactors are used for high power applications. They allow a lower voltage and current to switch a much higher power circuit, so they are generally larger and more heavy-duty than control relays, enabling them to switch higher power loads on and off for many thousands of cycles (Figure 1).Click to see…

Similarly, it is asked, what is the purpose of a contactor?A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.Beside above, why magnetic contactor is used? Magnetic contactors are a form of electrical relay found on most electrically powered motors. They act as a go-between for direct power sources, and high-load electrical motors in order to homogenize or balance out changes in electrical frequency which may come from a power supply as well as to act as a safeguard. Keeping this in view, what is the use of contactor in motor? A contactor is a large relay, usually used to switch current to an electric motor or another high-power load. Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts.What is the working principle of contactor? Operating Principle of a Contactor: The energized electromagnet then creates a magnetic field. This causes the core of the contactor to move the armature. The circuit is then completed between the fixed and moving contacts by a normally closed (NC) contact allowing the current to pass through the contacts to the load.
