I have this DOL starter. I want to use it to control a 3-phase, 7 HP water pump at my home. I would like to replace the mechanical switches (START & STOP) by relays. The relays will be controlled by a microcontroller (through isolators).
I don't understand what should be the rating of the relays. As per my understanding small sugarcube relays (240 VAC, 10 A) would be sufficient, as the relays will only be used for controlling the DOL starter. Please help me to validate my understanding, suggestions are welcome.
