Whole-supply monitoring for a 3-phase 415Y/240 V connection. Three 200 A clamp-on sensors read each phase independently, to the second, with ±2% accuracy. Add up to 16 branch-circuit sensors later.
What this model does
This is the base configuration: your total consumption, phase by phase. Three 200 A CT sensors clamp around your incoming mains — no rewiring, no interruption of supply — and report continuously to the free Emporia app.
It answers: what is my real load right now, how balanced are my three phases, and what does my consumption curve actually look like across a day, a shift, a month.
It does not yet tell you which individual machine or circuit is responsible. For that, add 50 A branch sensors — as a bundle, or as accessories later. The monitor supports up to sixteen.
