Overheating Pro1PM when drawing 234V, 3,000W - 12.82A?

Due to the fact, the Shelly pro 1PM has only one N terminal, it is IMHO hardly possible to route a neutral wire through the device. But a close distance to other components (Shellies, relays, fuses) in the fuse box may increase the internal temperature, which is measured by a NTC nearby the internal relay.

What is the installation situation (ambient temperature, space to the left and right of the Pro1PM)?

what does the output of http:/DeviceIP/rpc/Shelly.GetStatus say?

This occurred today:

I will get a thermometer into the panel.
