DOL Starter Connection with Indicator | 3 Phase Direct On Line Starter/ Explain with Circuit Diagram

Direct On Line (DOL) starter is the most fundamental, economical, as well as a simplest method for running a three-phase induction motor. In here, I have explained three phase DOL starter with indicator lights for induction motor. The Direct On Line Motor Starter (DOL) consist a MCB, Magnetic Contactor and a thermal overload relay for protection.
The applications of DOL starters are primarily motors where a high inrush current does not cause excessive voltage drop in the supply circuit (or where this high voltage drop is acceptable).

If you have any questions, please comment below the video. I will answer your questions.

Thankyou for this video. Was working on somthing similar - upgrade cable size for 11kW DOL ventilation fan motor with zero schematics/SLD in place. This really helps

Hilo sir you ah diagram 3phase motor control alternate run operation thank you

[desityniranjansss]

Thanks for the vedio and very useful for me

[liewyingket]

how you made this animation explanation so clear

[MATHSimpleProblems]

Kindly upload a DOL STARTER with OVERLOAD RELAY...FLOATLESS RELAY for pump and TIMER

[.f.u.n.]

I think it safer if power supply start from mcb to switch and then to relay contact in contactor, then proceed to overload relay and lastly to indicator lamp. Plus it will be more neat and easy to look at it.

How do you power up the OL yellow trip indicator? Won't you need a jumper wire on the OL Relay N.O & N.C aux.?

[rogerdavid]

when i working as an electrician, the run light was green not red, red was tripped, and yellow was off.

[elohorolokpa]

Please, what's the working principle of this connection.
Will the 3 phase motor turn on automatically?
