Yokogawa 250340LSRL7 Panel Meter Current Transformer

The Yokogawa 250340LSRL7 panel meter is an analog, CT-operated ammeter that provides a visual indication of AC current in control panels and power distribution systems by reading a 5A current-transformer secondary. Because it measures indirect current via external CTs, its display is an analog dial with a needle, and the measurement range is determined by the connected CT ratio (for example 0–100A or 0–500A). This panel-mounted instrument is part of the Yokogawa 250 series (New Big Look design), housed in a dust-resistant, gasket-sealed enclosure and offering typical accuracy around ±2% of full scale with AC operation from about 25 to 400 Hz. It is commonly used in motor control centers, substations, generators, switchgear, and other industrial control panels where safe, accurate monitoring of high-current loads via CT input is required.
