Hi Mara099, perhaps the relay is not the type you use, because this one of the image seems to be of the amperometric type and NOT PTC that today is the most common found. The phase connection to the relay, by the brown cable, is not what it seems, in fact the image only indicates a kind of connection point outside the relay coil circuit, this is a terminal or terminal block connection, that does not have a direct relationship with the relay, it is possible to notice the image carefully, more closely, it can be noticed, that it has no internal physical connection with the rest of the relay elements, nor with its magnetic coil that works by amperage, hence its name, I repeat that connection to the relay, it is only a meeting point and nothing more, from that point the connection to the thermostat follows, without entering into the relay, and from the thermostat, to the thermal protection, which then ends at the terminal common compressor itself. At the time of starting, the magnetic coil of the relay is energized, so that the bridge that joins the contacts or pins # 4 and # 6 is raised inside the relay itself, once the compressor starts, the amperage drops, and with it the bridge that connects the ping # 4 and # 6 descends, to be powered by the compressor, by the neutral phase or celestial cable, which passes through the magnetic coil inside the relay, which connects the compressor's running terminal with said coil, by the ping or terminal # 5 of the relay itself. If you still have doubts, please comment. Luck. S @ lu2 friovega63.
