Yokogawa 250340LSRL7 5 Amp Current Transformer Panel Meter

Description:

The Yokogawa 250340LSRL7 panel meter is an analog current meter designed for use with external current transformers (CTs) to measure higher AC current levels in industrial systems. Commonly installed in control panels, switchgear, and power distribution systems, this meter provides accurate visual indication of current flow based on a 5A CT secondary input. Maintenance teams and electricians use this unit for load monitoring, diagnostics, and replacement of legacy transformer-rated panel meters.

Applications:

The Yokogawa 250340LSRL7 is widely used in industrial and commercial environments requiring indirect current measurement via CTs. It is commonly found in motor control centers, generator systems, substations, and electrical distribution panels where monitoring high current loads safely and accurately is critical.
