Hello Faustino, right now I could not tell you what the capacity of your compressor is, because it would be necessary to search on the internet, for the model that says on your chapilla or informative label. The compressor brand would be (KULTHORN) and the model would be (C-BZN176L2Z) with that information, its capacity and consumption may be found. Obviously, or the compressor is damaged, or maybe it bursts the capacitors, because the relay you are using does not have the corresponding divisions in its contacts so that a starting capacitor is connected to it like the one you are trying to connect. If the order of the connection in the compressor terminals, common bone, running and starting, is well located, you can test the compressor directly, using the thermal protection of the same compressor, to know if the latter is really damaged or not, if the protection does not trip after starting the compressor for a reasonable time, it would mean that it is not damaged and what happens, is that it does not connect the capacitor well, constantly sticking the same, bone permanently as a way of Electrolytic capacitor, without obviously being it and that is why it heats up to bursting, or the repeat relay, which you are using, is not designed for the use of starting capacitor and must in that case adapt the relay itself for that connection, making it the corresponding internal division, so that in a row that the compressor can start, the connection to the compressor start and the capacitor itself is opened, or it should get a n relay with the appropriate design so that this type of capacitor can run smoothly with the relay itself used and the compressor of your equipment. If you still have doubts, please comment. Luck. S @ lu2 friovega63.
