    Hello,
    I am a lucky buyer of 3-phase 3-phase motor.
    I also have a star triangle switch.

    Now I have a problem how to put it all together. Unfortunately, I can not find the diagrams for this engine or the circuit breaker. It looks like someone has already bridged the star on the engine. Is there any less power then?

    Paramters 3kW, 4HP 220/380, Y / ?

    I am enclosing one by one.

    This motor is not suitable for operation with the Y / ? switch.
    As you have noticed, the order of switching on is Y and ?, and on the motor plate you have the opposite, i.e. ? / Y.
    Do you have such a poor installation that you can start the 3KW engine with start up?

    The installation should be easy to manage, but I have a switch like that. Is it possible to connect it so that it works without a boot?

    If I can ask for an explanation of what does ? / Y mean on the plate? (Of course, in this case - 220/380)

    Thanks

    Buddy, this engine can not work in delta connection because you get it.
    In connecting to a triangle, the network layout would have to be 3 X 220V and you probably do not have one.

    There is a good chance that it will. But you would need to test this switch a bit - the description and appearance does not say anything.

    Ok, tomorrow I'll stick with the meter and see what it's there :)

    Thanks again!

    I have a meter with a pipe ;) and I just measured the switch.
    On Y
    1 contains 2
    4 -> 8.12
    9 -> 10
    Na ?
    1-> 2.4
    5-> 8
    9-> 10.12
    I do not know where to connect L1, L2 and L3 now and where the engine ...

    Good night. Only ? (star :D ) Do you live in the US? As colleagues wrote, there is no possibility of this type of start-up (? / ?) in the classic European network (except perhaps Norway)

    The switching order is determined by the star / delta switch and not the motor nameplate. I have never seen the triangle / star switch. This engine can not work in our Polish network connected in a triangle. It can work only on a star. The switch probably can be connected so that it serves as an on / off switch. Just an ohmmeter or a battery with a bulb, and an analysis of which contacts are closed.
    Answering and right.

    It's best if you take down all the bridges and measure again.
    Put a photo of the switch's top, please, because I'm still not telling me anything.
    If you want to use this switch only as 0-1 then I suggest: L1 to 1, L2 to 4, L3 to 9; and the motor: U1 to 2, V1 to 8, W1 to 10. It is necessary to block the possibility of switching to the third position because it will be short-circuited.

    Added - number 5 in the original post.

    This is probably the biggest problem I see.
    I found it separately in the barn and there's a 0-1 switch on it, so I'll start with it.
    If everything works well, maybe it will invest in something like:

    Just as the Colleagues wrote. This is not a switch to such an engine and you should not make any combinations, but buy a normal 0-I motor switch
    I close the subject.

Topic summary

The discussion revolves around the connection of a 3kW, 4HP, 3-phase motor using a star-delta switch. The user is seeking guidance on wiring the motor correctly, as the motor's nameplate indicates a different switching order than the switch they possess. Responses indicate that the motor cannot operate in a delta configuration due to the voltage supply limitations (220/380V) and that it should only be connected in a star configuration. Suggestions include measuring the switch contacts and using it solely as an on/off switch, with specific wiring recommendations provided. The consensus is that the current switch is unsuitable for the motor, and a standard 0-I motor switch is recommended for proper operation.
