Data Sheet

NEW “A SERIES”

CURRENT TRANSFORMERS

• Series from 20A to 600A primary current

• Class 0,5 and Class 1 accuracy class

• Design and production accordance with

international standards

The new “A Series” current transformers carry the

quality of ENTES to the first point of measurement.

ENT.A30 and ENT.A40 series current transformers

ensure measuring currents with the highest

accuracy.

Thanks to 5A secondary current, the new “A Series”

current transformers can be safely used together

with ENTES devices in both PFC and Energy

Efficiency product groups.
