Does anybody know where I can find a capacitor like the one in the picture? It has three cables coming out on top and is used for an electrical cable winch. Wasn't able to find one neither on ebay nor on alibaba, but they must be out there somewhere!

The little circuit diagram on the side indicates that it is two capacitors in one case, hence the three leads. This would usually be called a 'start and run' or 'dual' capacitor, because it uses different values for starting and running the motor.
I believe CBB60 refers to the insulation type used, not very critical. The more important information is the capacitance of the two capacitors of 10uF and 40uF. The voltage is also not so critical, but it needs to be above the working voltage of the motor. 450v is probably a safe number, but something around that or greater would be fine. If you can't find a combined unit with the correct combination of capacitance you could replace the one capacitor with two separate capacitors. Be very careful working with capacitors. They can store a lot of energy, even when the device is disconnected. Do not touch the leads until the capacitors (both of them) have been shorted to dissipate the energy using a insulated tool of some sort.

Seems hoist capacitor is the key word resulting in 3 lead finds finally.

You could always email the manufacturer of the winch and ask them, or failing that the manufacturer of the capacitor, Taizhou Fuye Electronic Co., Ltd (sales@tzfuye.com).

Infact I already contacted the hoist manufacturer asking for spare parts, if necessary I would buy two complete control units (the capacitor sits inside).
So they sold me two units. But they were different, as they only had four wires unlike my original ones with five wires. Also the capacity was bit lower and the capacitor itself had four cables unlike mine with three cables. They had done some changes meanwhile.
I asked if it was possible to get the original parts as spares but still waiting for an answer.
I already tried to search for LMG, but german google did not bring me the company You mentioned. On their website I was able to find the right type of capacitor now.
So I´m going to contact them directly.
Thank You very very much for that hint! That was the kind of answer I was hoping for!
But thanks to the other contributors, too.

Just buy two capacitors. One 10uf and one 40uf.

I could do that. Or I just use the two, the manufacturer of the hoist already sent me, but they're different ones. They have four cables and are connected differently. And since I'm not really an electronics expert, I would rather copy the same set-up. I know that capacitors can do a mess when installed or used the wrong way. For now I´m still waiting for answers from both manufacturers.

Just in case somebody is curious about the different set-ups. Original: Replacement I got: The reason why I want to copy the whole set-up: I'm using two hoists on a portal frame, currently with two manual control units. For some jobs it would be better to have both hands free for other tasks, so I want to chose between manual and pedal control units. Changeable with Neutrik power-con connectors while the capacitors are loaded! edit: I made a simple diagram for better comparison of the two different control units I have:

What you have there will work fine. The 3 wire just has the negative side of the two capacitors connected internally. (We call that the 'common') The 4 wire doesnt have them connected internally so just connect both of them to the same terminal externally.
The only thing you might have trouble with is determining which of the positive red wires goes to which capacitor without having a capacitance meter to test them. However looks like one is marked with an R so guessing that will be you Run capacitor and other other is your start. The start is switched by the motors centrifugal switch. The run is always connected across the windings. You could work back through the replacement units wiring to work it out what's what too.
You will have to do a bit of thinking to find which colour wire from the motor is which I think. It's not obvious from the diagram alone but ultimately you should just be able to swap those capacitors like for like. I don't think 5uf will make much difference.
Google for a single phase motor with start winding diagram to help you.

Both the original and the replacement have a tolerance of 5%, so they could be practically the same value. Go ahead and use it with the two black leads commoned together as slater says.
It's not clear from the photo, but is there a marking (an R?) on the end where the leads are that indicates which lead is which capacitor? The old one presumably has 1 and 2 marked on it as per the diagram?

Still no answers from China or Austria, so I might need to use the caps I have. It was once explained to me that the stronger capacity would be to start lifting heavy loads and the lower capacity for releasing? Anyway, I made pics of the top of both caps and yes there is an R on the four cable version. Both black cables go to the UP part of the switch, both reds connected to DOWN.
