Panel Meter for AC Current 0-100 A

This analog panel meter measures alternating current from zero to one hundred amperes using a moving-iron movement. It is designed for panel mounting in electrical enclosures where a direct-reading AC ammeter is required. The 2.5 inch case fits standard cut-outs and the polycarbonate window protects the scale.

Upgrade from Estimated or Indirect Readings

Replacing a clamp meter or calculated estimate with this panel-mounted instrument gives continuous, at-a-glance monitoring without opening the enclosure. The jump is worth it when a permanent, dedicated display is needed for troubleshooting or compliance logging. Accuracy is rated at plus or minus 1.5 percent of full scale.

Simple Panel Mount with External Transformer

Installation uses the supplied mounting template and screws; the meter connects to an external five-ampere current transformer rather than the primary conductor. A common error is wiring the primary circuit directly to the meter terminals instead of through the transformer. The glass-filled polycarbonate case meets UL standards for panel integration.

Questions about this item

What size panel cutout does the 2.5in meter need?

The 2.5in case uses a 10 percent glass-filled polycarbonate body and the box includes a mounting template to mark the exact cutout.

How is the meter wired for the 0-100 AC A range?

Connect the circuit through an external 5A current transformer, then run the transformer secondary leads to the meter terminals.

What ongoing check does the moving-iron movement need?

Verify the pointer reads zero with no current applied; re-zero using the front adjuster if it has drifted beyond the 1.5 percent full-scale accuracy.
