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.
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).
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.
How does a shading coil in a contactor actually work?
A shading coil in a contactor is used to hold the AC contactor's pole faces closed during the transition of the voltage through the zero voltage phase of an electrical cycle.For an excellent description see related links below.
How do you test a good and working contactor?
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.
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 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.
Can 240v coil contactor be connected to 110v supply?
no
How do you wire a 230 volt contactor with a 110 volt coil?
To wire a 230 volt contactor with a 110 volt coil, you need to connect the 110 volt power supply to one terminal of the coil and the neutral wire to the other terminal of the coil. Ensure that the contactor is rated for use with a 110 volt control circuit. Additionally, verify the wiring diagram provided with the contactor for proper connection details.

What is the part of the contactor that gets magnetized by the relay coil is called what?
The part of the contactor that gets magnetized by the relay coil is called the armature or plunger. This is the component that moves when the relay coil is energized, causing the contacts to close or open depending on the design of the contactor.
What is the function of an electrical coil in a basic circuit?
There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.

What should the resistance on a 30 amps triple pole contactor measure?
If the coils pulling the contactor in, you should have negligible resistance. If the contactor is not in, then you should have open circuit. Unless your measuring the resistance of the coil, in which case it will roughly be around 30ish ohms im guessing, depends on the coil voltage
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.
How many switches can be connected to a contactor coil control circuit?
unlimited
