Phase-level data shows when one phase is carrying most of the load. That is useful before adding a large appliance or an EV charger.
Questions about this one
Does it need three-phase power?
It is designed for three-phase boards. Single-phase use is possible but wastes two channels.
Can it control loads?
No. It monitors energy; switching requires separate relays or smart plugs.
The details
Built for the board.
The DIN-rail enclosure and external clamps suit a permanent installation. It is not a plug-in monitor.
