In order to forward reverse 3 phase induction motor up to 10 Hp via DOL starter , the required control circuit is given below
Required components are
- 1 off push button
- 2 on push buttons
- 2 Main Contactors 4 pole(110V coil voltage or 230 V coil voltage)
- 3 Indication lamps (110v/230vAC)
Depending upon your control circuit voltage choose coil voltage of contactor preferably 110v,230V.
Indication lamp voltage should also be the same
Diagram Description
- MC1 - Main contactor 1
- MC2 - Main contactor 2
- NO - Normally open
- NC - Normally closed
- Parallel NO connection to On buttons will give holding for the respective contactors
