RS PRO Analogue Panel Ammeter 250 A AC, 45 mm x 45 mm, 1 % Moving Iron 186-2421

RS PRO 186-2421 Analogue Panel Ammeter 250 A AC, encased in a moulded polycarbonate housing measuring 45 mm x 45 mm, is a precision moving iron meter engineered for reliable AC current measurements in industrial, laboratory, HVAC, and manufacturing environments. With an accuracy of 1%, this meter provides highly accurate readings essential for process control applications.

The instrument features a knife-edge pointer with deflection ranging between 0° to 90°, enabling clear and precise indication of current values. It supports measurement ranges from 100 mA up to 100 A direct connection and can be utilized with CT ratios such as 250/5 A to measure higher currents.

Designed to tolerate harsh conditions, it withstands shock resistance up to 15g for pulse durations of 11 milliseconds and operates effectively within a temperature span of -10°C to 65°C. The ammeter carries multiple certifications including VDE 0100-410, IEC 61010, UL 94 V-0, and complies with EMC and low voltage directives, assuring quality and compliance for industrial safety standards.

The meter is housed in a compact, moulded square case compatible with DIN style panel cutouts, making it ideal for integration in control or switchgear panels within machinery consoles. It ensures true RMS value measurement and operates effectively over a frequency range of 15 Hz to 400 Hz, making it highly versatile in various electrical systems.

Its scale is calibrated for up to 500 A with available overload scales of X2, X3, X5, or X6, facilitating the measurement of motor inrush currents. The relative humidity suitability is less than 75% annual average (noncondensing), ensuring stable operation under varied environmental conditions.

Measures AC currents up to 250 A with 1% accuracy. Compact square polycarbonate case with 45 mm x 45 mm cutout dimensions. Operating temperature range from -10°C to 65°C. Features knife-edge pointer deflection from 0° to 90°.

Shock resistant to 15g for pulse durations of 11 milliseconds. Overload capacity up to 2 times nominal current continuously. Rated for voltages up to 600 V DC and 1000 V AC. Suitable for mounting in control and switchgear panels in industrial machinery.

Complies with multiple international standards including VDE, IEC, and CE certifications. Provides true RMS value and is substantially waveform independent.

This RS PRO Analogue Panel Ammeter is an optimal solution for electrical, automation, and process control engineering, ensuring accurate current readings for industrial machines, HVAC systems, manufacturing lines, and laboratory instrumentation.
