Maybe more effective than one meter special power cable?

The actual name for the connector is “modular connector”. Yes, the name sucks, using generic adjective isn’t a good idea for naming things, but just FYI to help search. Further piece of the name is 8p8c, or 6p4c, or 6p2c, depending on how many contacts the plastic housing has, and how many are actually populated with the contacts.

Now <0.5A definitely isn't a problem of heating too much

The active resistance of UTP is about 1O \$\Omega\$ at 10m = 2 \$\Omega\$ in both directions.

The thing that kills RJ45 contacts (and most connectors) is sparks/arcing when connecting.

And PoE also protects against this – power is not supplied immediately, but after load matching.

Three Phase Ethernet!

3ph 230/400VAC, 16A. I don’t think that little rj45 will handle what the other thing’s gonna give it. (~10kW max)

“Please observe all arc-flash safety precautions.”
