Can I use 3 Shelly pro 4pms to monitor consumption of device that may actually use 400v and not just 3x230v?

Not really! With three Shelly pro 4PM devices connected at three phases, measuring of power factor isn’t possible, cause the devices don’t share this value with each other. You may measure apparent power only.
Another question: Do you really have a voltage of 400 volts between phase and neutral?

Wouldn’t a Shelly pro 3EM do the job?

I do already have 3 4PMs. So it would be easier and I would avoid using clamps in tiny space I have in distribution box ...
