A contactor is tested by using a device called a Multimeter. By setting the multimeter to ohms and rx1 you can clip both prongs to the coil. If the multinmeter moves the contactor is good. If it doesnt move its bad.

What is the difference between an definite purpose contactor and a lighting sontactor?
A definite purpose contactor is designed (and rated) for a specific load. So a lighting contactor is one example of a definite purpose contactor. A motor starter contactor is another example. So, a lighting contactor is a definite purpose contactor, but a definite purpose contactor is not necessarily a lighting contactor (it might be a motor starter, for instance).
Can you use an AC contactor in the place of DC contactor?
No, you definitely cannot.
How is a Blowout coil connected?
A blowout coil connected in series with contactor's auxiliary contacts that shunt around the main contactor contacts. The coil is out of the circuit when the main contactor contacts are closed and in the circuit when the main contactor contacts are open.

How do you activate 240v coil using a 240v contactor?
The coil can be operated by taking one leg of the 240 volts from the top of the contactor and connecting it to one terminal of the coil. Take the other leg of the 240 volts from the top of the contactor and connect it to the device used to turn the contactor off and on. From this switching device take the switched wire and connect it to the other terminal on the contactor's coil. Now when the switching device is activated the contactor will open and close.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Definition of coil in contactor?
The coil in a "Contactor" is essentially an electromagnetic coil that provides the driving force to close the contacts in a Contactor. When the "Coil" is energized by a lower control voltage usually from some type of controller such as a PLC, the Normally-Open contactor will close or in the oposite case, the Normally-Closed contactor will open.
How do you test if an amd CPU is working without the use of a motherboard?
There is no good way to test a CPU without putting it onto a compatible motherboard.
How is a Blowout coil connected?
A blowout coil connected in series with contactor's auxiliary contacts that shunt around the main contactor contacts. The coil is out of the circuit when the main contactor contacts are closed and in the circuit when the main contactor contacts are open.
How many wires to control a mechanically held contactor?
A contactor is a type of switch. However this switch uses electricity to power an electromagnetic coil to switch on or off power. Hence a contactor needs 2 wires - A live/hot wire and a neutral wire. Generally these are connected across the A1 and A2 terminals of the contactor.
If you have a bad compressor does that mean you need a new contactor?
Not always. But if a compressor goes bad it can take out the contactor. I have replaced compressors before and found the contactor is still ok. In a commercial application Copeland will not honor the warranty if the contactor is not replaced at the same time a new compressor is installed. Not sure about residential but for a $15 contactor I would not gamble with it.
What are contain in contactor?
