[QUOTE="mygoggie, post: 965099, member: 18916"] The isolator must be 20A and be L+N. Normally a circuit breaker will be cheaper and is actually a better option. The one you choose is incorrect. The circuit breaker rating will depend on the pump wattage, which normally is a less than 1 kW pump. In this case then the amp rating will be 1000 W / 230V = 4,5A upscaled to 2x for startup amps to 10A then. So the circuit breaker will be a single pole 10A C-curve. The one you choose is incorrect. The relays must be 230 V at 10A on the switching side and 24V DC on the coil side. The one you choose looks to be correct. The relay base - You need to check if the base can handle 10A at 230VAC. I cannot find such details. Hope this helps! [/QUOTE]
