Value Brand Analog Panel Meter AC 0-75A 3.5in 12G389

SKU CH-3H02-Z32EC

Analog panel meter measures AC current from 0 to 75 A with 1.5 percent accuracy in a 3.5 inch polycarbonate case

  • Product typeElectronic
  • Measures AC current up to 75 A for high-load monitoring
  • Moving-iron movement delivers ±1.5 % accuracy across the scale
  • 5 in case fits standard panel cut-outs
  • 10 % glass-filled polycarbonate housing resists impact and heat
  • Includes mounting template and screws for quick installation

Purpose and audience

The Value Brand Analog Panel Meter measures AC current from 0 to 75 A with a 3.5 inch dial. It suits electricians, panel builders and maintenance teams who need a local readout on switchgear or control boards.

Thermals noise and power

Moving iron movement draws negligible power from the measured circuit and produces no audible noise. The 10 percent glass filled polycarbonate case resists heat without active cooling. Accuracy is rated at +/- 1.5 percent of full scale.

Upgrade path and fit

This meter replaces worn analog indicators or adds metering where none existed. The jump is worth it when a panel needs a direct reading without a separate transducer. It requires an external 5 A current transformer and a cut out matching the supplied mounting template.

Questions about this item

How do I install the 3.5in analog panel meter and what step is often missed?

Cut a 3.5in panel opening, use the supplied template to mark screw holes, then secure the meter with the included mounting screws; the step often missed is wiring the AC circuit through an external 5A current transformer instead of connecting line current directly to the meter terminals.

What maintenance or replacement will the meter need later?

The moving-iron movement and polycarbonate window are sealed for the 1-year manufacturer warranty period; after that, plan to verify the +/-1.5% accuracy annually and replace the unit if drift exceeds the spec, as no user-serviceable parts are inside.

What limit appears first during sustained 75A monitoring?

Continuous operation at the 75A full-scale reading relies on the external 5A transformer staying within its thermal rating; the meter movement itself is rated for the range, so transformer heating is the practical limit that shows up first.
