What is a contactor coil?
a contactor is generally looks like a small box connected to an electric circuit. it is what controls electricity flow to a motor. in the middle is normally a way to push in the contactor to manually check to see if either the motor works or if you have electricity.
How to choose rating of contactor in star delta starter?
As well as motors, contactors also have kW and Ampere ratings. Have a look on the name plate of your motor and you will see its maximum current draw (amps). Select a contactor with a current rating greater than this.
How do you select contactor for 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 which are of the magnetizing coil. By magnetizing & demagnetizing A1-A2 coil, power line connections to motor can either be made or broken. This is a simple DOL (Direct On Line) application. Further, reverse/forward circuits and star-delta circuits can be constructed based on the requirement. A contactor's role in whatever application is 'making or breaking' the contact. The coil supply can either be AC or DC.
Which is good demand among ece and mechanical engineering?
let look from the different angle, mechanical engineering and ece has almost equal scope but mechanical have little higher because mechanical has wide variety of subjects and every skilled mechanical engineer has got statisfyed job.... now we look from ece,ece is the easy to learn and has good job outlook,every professsionaly skilled engineerhas good job aspect...

Why does the air conditioning compressor keep operating long after the system is turned off?
The contactor on the outdoor unit is probably stuck. Disconnect the power to the indoor unit, then disconnect the power to the outdoor unit and take a look at the contactor.

What is interlock fabric how it is knitted?
Interlock fabric is a variation of rib knit construction. Similar to a Jersey knit except both front and back of the fabric look identical. Double knit construction makes this a thicker knit fabric. Interlock is the tightest weave, gives the smoothest surface and the finest hand. The fabric is extremely soft, firm and absorbent.
