Moving-iron meters AC

Application

EA16, EB16, EA17, EA19 and EA12 moving-iron meters are intended for measuring AC voltage or AC current. These meters measure the true RMS value and their indications are highly independent of the measured value curve shape.
EA16, EA17, EA19 and EA12 meters are designed for mounting into panels. EB16 meters are adapted for a fast assembly rail mounting (35 mm rail) in compliance with EN 60715 standards.
EA16, EA17 and EA19 meters are designed to interchangeable dials.

TECHNICAL DATA
Accuracy class 1.5
Measured value frequency 40...45...65...72 Hz
Execution of ammeters normal scale version or version with
100% overload. Other overcurrent
scale, on request after agreement.
Self-consumption see table 1
Matching the measurement range of the meter to transformer ranges by exchange of the dial. The dial is put forward the slot in upper case side.
Note: EA12 (144 x 144) meters are not provided for interchangeable dials
