Re: Brand new DYN4 400W set - goes in Overcurrent fault as soon as motor is connected
If you are asking only about the contactor, there are 3 parameters to concider. Switching voltage, switching current, and coil voltage. Most contactors are rated at a minimum of 250V, switching current is stated as is the coil voltage. The switching voltage and current need to be compatible with the drive, the coil voltage needs to be compatible with your control voltage.
An example of contactors that would work.

Don't forget to add the proper circuit breakers ahead of the contactor(s) per the DMM installation instructions.
