Yokogawa 250-240-NGNG Analog Ammeter Panel Meter

The Yokogawa 250-240-NGNG analog ammeter panel meter delivers real-time AC current readings from 0 to 20 A for panel-mounted use in industrial electrical systems. Commonly installed in control panels, switchgear, and power distribution systems, this iron vane–based meter uses a self-contained AC measurement mechanism and presents a clear analog dial with a needle pointer for quick visual monitoring. It operates over approximately 25–400 Hz and includes external magnetic shielding to minimize interference, while its dust-resistant, gasket-sealed construction (New Big Look series) suits harsh industrial environments. Accuracy is typically ±2% full scale, making it suitable for monitoring load conditions in electrical panels, generator systems, motor control centers, and switchboards to support safety and system performance. When upgrading or replacing legacy meters, note that Yokogawa offers the 250-240-LSMT as a transformer-rated variant, with higher-range variants such as 250-240-LSNG / LSNL also available.
