Overview
The General Electric 50-103131-LSSV1 is a panel-mounted AC ammeter designed for precise current measurement in industrial and utility applications. With a 240:1 current transformer (CT) ratio, this AB-40 meter provides a 5A full-scale deflection that corresponds to 0–1200A on the primary circuit. The instrument features a robust zero-left scale design typical of GE switchboard instruments, enabling straightforward reading in high-current environments.
