What this module measures and where it snaps in
The 3UF7111-1AA01-0: Rated for line-to-line voltages from 110 V to 690 V AC at 50 or 60 Hz, it covers standard low-voltage motor and distribution circuits without an external PT. Energy measurement accuracy is ±5 % from 2.25 A to 80 A, and ±10 % from 80 A to 320 A, across the full voltage range and power factor 0.5 to 1 — adequate for submetering and load profiling in a control panel.
Mounting, wiring, and environmental limits
IP20 rated, so it belongs inside an enclosure, not on a washdown line. Vibration resistance is 1–6 Hz / 15 mm and 6–500 Hz / 2 g with the basic unit snapped on — derated to 1 g above 6 Hz when mounted alone.
