I have a 3 phase waterpump that I would like to switch on and off remotely(gsm or wifi, will still decide which will suit me best)
My waterpump is 100% correctly installed with a phangle (load protection), with a magnetic contactor that is switched on and off by a simple "trip switch".
1.5kw motor, 380Vac.
My question... what is the best way to connect and use my arduino to remotely operate the "trip" switch?
Relays off course, or maybe some mechanical "hack" to just operate the physical switch?
All inputs and suggestions are greatly appreciated.
