Single-phase electric meter
, applied to active power measurement: accurate measurement, modular and small size (18mm), can be easily installed in various terminal distribution boxes. Rail type installation, bottom wiring, perfect match with miniature circuit breaker. The intuitive and easy-to-read mechanical display reduces the risk of data loss due to accidental power failure. No external power supply is required, and the operating temperature range is wide. It is suitable for commercial buildings and public infrastructure buildings to realize the measurement and statistics of electric energy consumption in different areas or different loads in buildings.
