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 with thickness not exceeding 25 mm in the holes according

to figure 3 and 4. 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.
