Single phase 240v motor starter & overload with on/off switch wiring
Hi,
Hoping you all can help me wire up my single phase 240v induction motor. Can someone please explain or even better sketch out where the wires need to go, I have a fair idea already just want some good advice before I continue.
Thanks in advance!

Single phase motor on a three phase contactor.
A1 and A2 are the contactor coil.
13 and 14 are N.O. contacts.
21 and 22 are N.C. contacts
95 and 96 are N.C. overcurrent trip contacts
Need the specs on that switch. Cutsheet or make and model.
The numbers don't mean anything.

Being single phase with the 3 phase overload heater, you need to jumper from T2 to L3; apply line voltage IN to L1 and L2. Motor goes to T1, and T3. Set the little adjustment wheel to FLA for the motor.

@ geochurchi.... Siemens LC1D12 contactor.
That's a typical off shore product with little to no technical information. Your wiring there is very easy but I don't know the functions of terminals 1, 2, 3 and 4 on that switch. I searched for half hour and found nothing on it's connections. I can't give you the final diagram until I know what those terminals represent.

Take a meter and ohm the switch. Two of the contacts will be connected. Those should be the red stop button and open when the red button is pushed.
The other two should be open and become connected when the green start button is pushed.
