Zoro Select 12G387 AC Current Meter

The Zoro Select 12G387 is an analog panel meter that measures AC current from 0 to 50 AC A. It uses a moving-iron movement and delivers accuracy within +/- 1.5 percent. The unit is built for panel mounting in electrical enclosures and industrial control panels. It carries UL listing for code compliance.

Panel Mounting and Transformer Use

The meter fits a 3.5 inch panel cut-out and includes a mounting template with screws for installation. Its case is made from 10 percent glass-filled polycarbonate with a polycarbonate window. Operation requires an external 5A current transformer that must be supplied separately. The meter itself does not connect directly to the measured conductor.

Replaces Basic AC Ammeters

This model replaces older analog ammeters that lack UL listing or offer wider error margins. The 1.5 percent accuracy class suits applications where tighter indication is required. It is not suited for DC measurement or for direct connection without a 5A transformer. Buyers needing digital readout or data logging should consider other instrument types.

Questions about this item

What is the accuracy tolerance of the 0-50 AC A measurement range?

The meter reads within ±1.5 % of full scale across the 0 to 50 AC A range.

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

The moving-iron mechanism produces negligible heat; the glass-filled polycarbonate case stays near ambient temperature even after all-day use.

Which external transformer must be installed for the meter to function?

A 5 A current transformer is required; the meter cannot measure directly without it.
