RS PRO Analogue Panel Ammeter 25 A AC, 68 mm x 68 mm, 1% Moving Iron 186-2439

RS PRO 186-2439 Analogue Panel Ammeter is a precision instrument for measuring alternating current up to 25 amps within industrial, commercial, and laboratory environments. It features a robust moving iron mechanism delivering accurate current indication with 1% meter accuracy.

The ammeter is designed for mounting in control panels with a standard cutout size of 68 mm x 68 mm and a depth of 54 mm, housed in a molded polycarbonate square case that provides mechanical protection and electrical insulation.

This meter is calibrated for true RMS measurement and is largely waveform-independent, suitable for use with complex AC signals ranging from 15 Hz to 400 Hz frequency. The scale calibration down to 10% allows detailed measurement sensitivity with overload scales available up to 6 times nominal current, enabling accurate display of motor inrush currents.

Operation is reliable across a wide temperature range from -10°C to 65°C, and the unit withstands mechanical shocks up to 15g with a pulse duration of 11 milliseconds. It also maintains performance in relative humidity conditions less than 75% on an annual average basis.

Measures true RMS AC current with moving iron technology. Compact 68 mm x 68 mm mounting cutout suitable for panel integration. 1% accuracy with knife-edge pointer deflection from 0° to 90°. Robust polycarbonate enclosure rated UL 94 V-0 for flame retardancy.

Suitable for industrial automation, electrical control, and power monitoring applications. Compliant with international standards including IEC, VDE, UL, and CE directives.

RS PRO products provide reliable instrumentation solutions widely used in process control, automation, and electrical distribution systems across industrial manufacturing, commercial facilities, and laboratory setups.
