Having worked with machinery imported from China I would be extremely surprised if all the components are actually branded. A good chance they're just copied.

A DOL starter has a 230v control circuit in it.
Surely you are checking the machine is fit for purpose and safe, so as long as the panel and components carry a suitable IP rating for the environment and the correct warning labels are in place I cant see the problem

A DOL starter doesn't necessarily have a 230v controlA DOL starter has a 230v control circuit in it.

OK right must have misunderstood your statement, sorryI was just referring to the stand alone wall mount type, just showing an example where 230v control is used

These aren't classed as a control system under EN60204 and thus don't need to meet there requirements as they are simple apparatus.
This is why you can still buy them with 400v control.
I'm not sure I understand, 400v coil 230v control circuit, how does that work or have I totally misunderstood what you are saying?I thought they where?
EN60204
"Transformers are not mandatory for machines with a single motor starter and/or a maximum of two control devices (for example interlock device, start/stop control station)."
Although the coil voltage is 400v, the control circuit is 230v.
I think I'll be much clearer in my response next time as I seem to have been misunderstood
What about the coil? @400v the 230v control isn't going to pull it in.Well the voltage is 230v at the start and stop button, overload etc so the bit that controls it is 230v just my opinion
What about the coil? @400v the 230v control isn't going to pull it in.
So you are saying it's a 230v control circuit with a 400v coil? to me that's a 400v control circuitIt sure will if there is a different phase connected to the A2, the control circuit is the same wether it is a 230v or 400v coil the only change is the connection to the A2 of the coil
If the control circuit is connected across 2 phases then that control circuit will be deemed a 400v circuit, L1 at the start of the control ending up at A1 on the coil at A2 the other end of the coil is connected to either L2 or L3 the circuit will be 400v, if you have a coil rated at 230 v then A2 should be connected to N.It sure will if there is a different phase connected to the A2, the control circuit is the same whether it is a 230v or 400v coil the only change is the connection to the A2 of the coil
