YC-72 Amp Meter

YC-72 Amp Meter

The YC-72 Amp Meter is a panel-mounted analog ammeter designed to measure AC current in electrical distribution boards and industrial control panels. With a standard 72 × 72 mm front panel size, it provides clear pointer-based current indication for monitoring load conditions.

The instrument is typically used together with an external current transformer (CT) for measuring higher currents in three-phase and single-phase systems. It complies with IEC 60051 standards for analog measuring instruments.
