Yokogawa 250-440-MTNT Ammeter 0-10a Amp

Description:

The Yokogawa 250-440-MTNT ammeter is an analog panel meter used in industrial electrical systems to measure and display alternating current (AC) levels up to 10 amps. Commonly installed in control panels, switchgear, and power distribution systems, this meter provides a clear visual indication of current flow for monitoring and diagnostics. Maintenance teams and electricians use this unit for real-time system monitoring, troubleshooting, and replacement of legacy panel meters.

Applications:

The Yokogawa 250-440-MTNT is widely used in industrial and commercial environments requiring accurate current measurement. It is commonly found in electrical panels, generator systems, motor control centers, and switchboards where monitoring load conditions is critical for system performance and safety.
