Hi Every Body..
I am working on a 3-phase motor driven pump starter. A 480vac, 7.5kW, 60Hz motor is to be start when low pressure signal energized and stop when high energized. I am thinking of using a DPST latching relay in my control circuit. The problem that I should use a transformer and rectifier to safe my control circuit. I am confused with wiring these things. Could any one help in that...

Thanking you..:)

You are talking about working on a high-voltage, high-power circuit. This can be extremely hazardous for an untrained person to attempt. I very strongly recommend that you consult with a licensed electrician for this project.

There are already industrial control products to perform the functions that you wish, but it would be a disservice and endangerment to you to discuss that sort of thing here.
