How To Use Contactor Electrical
How To Use Contactor Electrical. This is important because these will in part, determine which contactor you use. A contactor is an electromagnetic device that is used for switching an electrical power circuit on or off.
For 3 phase motor we use some electrical devices for starting off and resetting the magnetic contactor is one of them thats why today we disuse contactor wiring with the complete explanation. Such duty contactors are used in resistive loads such as heaters and electrical furnace. These contactors have high electrical life.
So Provide The Power Supply To The Magnetic Coil As Per Requirement.
A contactor joins 2 poles together, without a common circuit between them, while a relay has a common contact that connects to a neutral position. The contactor is mostly used in applications where higher current carrying capacity is involved, while the relays are used for lower current applications. This contactor is designed for automotive or marine use.
A Wiring Diagram Is A Simplified Traditional Pictorial Representation Of An Electrical Circuit.
How to wire contactor, overload relay with motor/ power and control wiring. Contactor these diagrams are current at the time of publication check the wiring diagram supplied with the motor. The use of a contactor provides a level of isolation away from the high electric currents associated with those applications, protecting workers and equipment.
Connect The Main Power Supply Terminal With The Incoming Terminals Of The Contactor.
Either of the two start buttons will close the contactor, either of the stop buttons will open the contactor. Multiple power circuits can be controlled by a single contactor. The upper and lower conductor terminals and main contact system together form medium voltage part.
A Contactor Is An Electromechanical Control Device That Used To Make Or Break The Connection Between The Load And Power Supply.
For example, if you have two applications, both using the exact same motor, but in one case the motor will simply be turned on for long periods of time, while the other will be turned on/off constantly, you will likely use two different iec contactors for each application. The contactor’s role is to switch on or off the power supply to its connected output load. If current flows through the control circuit, the contactor switches and current also flows through the load circuit.
Large Electric Motors Can Be Protected From Overcurrent Damage Through The Use Of Overload Heaters And Overload Contacts.
But the device used for higher current carrying application is known as a contactor and the device used for lower current applications is known as relay. This should now open when light, close when dark. Collection of ac contactor wiring diagram.
