Use Notes
- Designed for DIN rail meter panels and distribution-board display applications.
- The meter data warns against use in frequency-conversion power supplies, inverter outputs or high-harmonic power environments.
- 1P and 3P versions share the same product family structure but are selected according to the circuit being measured.
