Contactors have both power and auxiliary contacts. We use the auxiliary contact to control magnetic system of contactor. When a heater , relay or a key warn the contactor it is energized and by the typical magnetic interaction it opens its closed power contacts.

Can 125v magnetic switch be used in 12v system?
If what you term as a "magnetic switch" is an electrical contactor, then the answer is yes.A couple things to keep in mind. I presume the 125 volts mentioned is the coil voltage of the contactor.The switched voltages and amperage or horsepower allowed by the contactor is on the contactor's nameplate. This is the maximum voltage that can be applied to the contactor which includes 12 volts.The amperage of the 12 volt device is not mentioned and this should not exceed the maximum allowed current of the lowest voltage rating of the contactor. This is especially true if the 12 volts is Direct Current. An example of this could be a starter on a car. When the starter starts to crank it could be in the neighbourhood of 300 amps DC. As you can see this would fry the contacts of a normal AC rated contactor.
The best protection from an explosive device is?
A. Isolation of the device
Is a magnetic disc affected by a theft detection device or magnetic theft alarm sensor?
a magnetic theft alarm sensor
What does L1 mean?
This word stand for Line1 <<>> On electrical equipment the terminal L1 is where the placement of the supply conductor is terminated. On three phase equipment, the terminals are identified as L1, L2 and L3. On an electrical magnetic contactor these terminals will be located on the top of the device. The terminations on the bottom of the device where the load is connected are designated T1 and again for a three phase equipment the designation would be T1, T2 and T3.
What is a child protection device?
A child protection device can be a number of things. It is basically any device that is made with the intent of protecting a child. Car seats, the things you block wall outlets with, and the caps on prescription bottles are all types.
Magnetic overload device are the most accurate type of device for electrical protection?
yes it is
What is Definition of magnetic contactor?
conclusion
What are the parts of magnetic contactor?
There are three main parts of a magnetic contactor. These include the power contacts, contact springs, and the auxiliary contacts.
How does magnetic contactor operate?
explain me about the contactor works with examples. if i want to control a motor with contactor. and how i can use contactor in loops with over load and circuit breakers.
What is contactor operation?
contactor is a controlling device unlike CB-protecting device. It is usually connected in series with the fuse.
What are contain in contactor?
contactor is a device for making and breaking current. it just behaves like a socket.
What is the Difference between a magnetic starter And a contactor?
Motor starter usually refers to the complete assembly, including enclosure, contactor, control transformer (if any), overloads, fuses (if any), etc. A contactor is really just an overgrown relay, and is just one component of a starter. That having been said, many folks use the two terms somewhat interchangably. So someone who says starter may mean contactor, and vise-versa. Go figure.
What can you do to provide separate electricity to your shared well?
You can build a control panel that utilizes a reversing magnetic contactor set up. These types of magnetic contactor have a mechanical interlock along with a electrical interlock. Have your separate feed from each house terminate on the top of each magnetic contactor. House one to contactor one, house two to contactor two. Parallel the feeds from the bottom of both contactors to the pump load. Depending on which house calls for water first that contactor will pull in and lock the other one out. Once the pressure tank demand for that house drops out the other contactor will pull in and fill that pressure tank.

Wiering diagram for contactor?
the uglys book is a good reference ,call the manufacture or go on line to find a manual
Why does an ac contactor need shading rings?
In a AC contactor, a shaded ring is essential to prevent it from buzzing twice a cycle. Ac contactor takes a input of alternating voltage resulting an alternating current and flux through its windings. So The contactor buzzes each time the magnitude of alternating magnetic field reaches zero. The shaded rings are provided at some part of the core. When the alternating flux cuts them the produce another alternating magnetic field which is out of phase from the main magnetic field. So the resultant magnetic field no more zero at the contacts and which prevents the contact from buzzing.
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.
