Yokogawa 250240LSSC AC Ammeter 0-400Amp Amperes

Description:

The Yokogawa 250240LSSC AC ammeter is an analog panel meter used to measure alternating current up to 400 amps, typically via a current transformer (CT). Commonly installed in electrical panels and switchgear, this meter provides accurate visual monitoring of high current loads. Maintenance teams and electricians use this unit for load monitoring, diagnostics, and replacement of legacy ammeters.

Applications:

The Yokogawa 250240LSSC is widely used in industrial environments requiring high-current monitoring. It is commonly found in motor control centers, power distribution boards, generator systems, and heavy industrial equipment where tracking load conditions is critical for performance and safety.
