It also provides isolation between low power circuit and high power circuits. A contactor has three components.
Ac Contactor Working Principle And Structure Xinli Electric
Electromagnetic contactor diagram. This includes power contacts auxiliary contacts and contact springs. What is magnetic contactor. Magnetic contactors are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from on and off state. How to wire a contactor. The contacts are the current carrying part of the contactor. It works similar to the contactor but low range of the ampere as compared to the contactor.
Amongst the wide range of products for sale choice electromagnetic contactor is one of the hot items. Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts. Therefore the operation of this contactor is safe compared to manual contactor. We survey the auxiliary contact like normally. The electromagnet or coil provides the driving force to close the contactsthe enclosure is a frame housing the contacts and the electromagnet. The main part of a relay is the electromagnet.
Electromagnetic relays uses an electromagnet to operate a switching mechanism mechanically. Design engineers or buyers might want to check out various electromagnetic contactor factory manufacturers who offer lots of related choices such as ac contactor magnetic contactor and contactor. Magnetic contactors are the same as the electrical relays which are used in a number of electric motors. The design of this type of contactor is most advanced among all other types of contactors. In this video i show you how to install a contactors wire firstly after that show how you can install a auxiliary contactor on the main contactor.

The construction and working of a relay can be understood from the above diagram. It requires a small amount of control circuit to turn on and off the load. Enclosures are made of insulating materials such as bakelite nylon 6 and. It uses very low power to control the high amount of. These lines far exceed the 120 volts ac standard in most homes. 240 volts ac and 480 volts ac are commonly used for these large pieces of.
Many large pieces of equipment are powered directly from high voltage lines. This is an electromagnetic type contactor and it can operate automatically. A contactor is a large relay usually used to switch current to an electric motor or another high power load. Introduction of the electromagnetic relays relays are basically an electromechanical switch which is used to switch on or off a circuit with the help of the electromagnet.
