Analog Panel Meter for AC Current

This ZORO SELECT analog panel meter measures AC current from 0 to 100 AC A with a moving iron movement. It provides a +/- 1.5 percent accuracy rating for monitoring electrical panels. The 4.5 inch case uses 10 percent glass filled polycarbonate with a polycarbonate window. It is designed for use with an external transformer.

Panel Mounting and Case Requirements

The meter fits a standard panel cutout and includes a mounting template with mounting screws for installation. Its Rish Vista case style is built from durable polycarbonate materials. The unit carries UL standards compliance for safety. An external current transformer must be supplied separately to complete the measurement circuit.

Measurement Range and Accuracy Limits

The 0 to 100 AC A range suits monitoring main feeders and large branch circuits in industrial panels. Accuracy holds at +/- 1.5 percent of full scale across the calibrated span. Readings beyond 100 AC A exceed the movement limit and require a different meter or transformer ratio. The analog display offers direct visual indication without digital processing.

Questions about this item

What is the accuracy tolerance when measuring 100 AC A continuously?

The meter maintains ±1.5 percent accuracy across the full 0 to 100 AC A range.

How much heat does the moving-iron movement generate during all-day operation?

The moving-iron mechanism produces minimal heat; the polycarbonate case and window remain cool to the touch.

Which external transformer ratio is required for the 0-100 AC A scale to read correctly?

The meter is calibrated for use with an external current transformer; select a CT with a 100 A secondary to match the scale.
