Magnetic contactor operation
WebA contactor consists of an electromagnet, a set of power contacts, and a spring enclosed inside an enclosure. Some of them have built-in economizers, that can reduce power … WebContactors. Contactors are used for the switch of electric motors, capacitors, lighting loads and other high-power applications that a relay cannot handle. The principle of operation of contactors is same as that of the relays. Contactors are designed to carry more current than the relays.

WebDec 15, 2024 · Electromagnetic contactors are composed by a magnetic circuit with solenoid coils and springs. When a voltage is applied to the solenoid coil, an electromagnetic force attracts a movable magnetic core toward the fixed magnetic core in order to close the main electric contacts of the device. WebMay 14, 2014 · The electromagnetically operated contactor is one of the most useful mechanisms ever devised for closing and opening electric circuits. Contactors are used to switch power ON and OFF to a distribution panel. They are also used with pilot devices to control the temperature and liquid level of a tank.
Webcontactor with overload relay. A magnetic starter is an electromagnetically operated switch which provides a safe method for starting an electric motor with a large load. Magnetic … WebThis can be done at the motor starter or at the motor itself. Three-phase motor rotation Once two of the lines have been switched, the direction of the magnetic fields created in the motor will now cause the shaft to spin in the opposite direction. This is known as reversing the phase rotation . Reversing Magnetic Starters

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. Unlike general-purpose relays, … See more A contactor has three components: • The contacts are the current-carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. Contact material is chosen for high electrical … See more Contactors are rated by designed load current per contact (pole), maximum fault withstand current, duty cycle, design life expectancy, voltage, and coil voltage. A general purpose motor control contactor may be suitable for heavy starting duty on large motors; so … See more When a series of contactors is to be operated in sequence, this may be done by a camshaft instead of by individual electromagnets. The camshaft may be driven by an electric motor or a pneumatic cylinder. Before the advent of solid-state electronics, … See more When current passes through the electromagnet, a magnetic field is produced, which attracts the moving core of the contactor. … See more Without adequate contact protection, the occurrence of electric current arcing causes significant degradation of the contacts, which suffer … See more Lighting control Contactors are often used to provide central control of large lighting installations, such as an office building or retail building.
