What is a contactor coil?

A contactor is an electronically controlled switch that has a coil  and contacts. The contactor coil moves the contacts into position  by energizing the contactor. A contact

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

How do electro magnetic contactors work?

    A contactor is an electrically controlled switch (relay) used for switching a power circuit.     an electro pneumatic contactor is similar to the above exce

How do electro pneumatic contactors work?

      A contactor is an electrically controlled switch (relay) used for switching a power circuit.     an electro pneumatic contactor is similar to the abov

How do electrical contactors work?

a contactor works in the sae principle as a motor THE SIMPLE INDUCTION LAW this law is when you twist an isolated wire (a simple wire inwhich every where can be found) around

What is a shading coil?

A shading coil induces currents to create an additional electrical  phase. The coil pauses slightly to control magnetic flux. Delaying  magnetic flux allows for a secondary

How does an electrical contactor work?

  An electrical contactor works like a remote switch, usually to switch higher voltage/current circuits.   A contactor has a set of normally open and/or normally closed

Shading ring in magnet of electrical contactor?

Best guess? A shading ring aborbs energy from a changing magnetic field, so I'm guessing it will slow the opening and/or closing time. Try a web search: electrical conta

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

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 fr

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 conta

How does a contactor work on an electric motor?

With a contactor we can control the power connection to the motor (power on/off). A typical AC contactor comes with 4 terminals aside (L1,L2,L3,A). 'A' has A1,A2 terminals w
