About AcuCT 5A Series

Why choose a 5A or 1A output current transformer?

Current transformers with a 1A or 5A output can be found across industrial settings and is a well-established standard. Power meters and other devices engineered for industrial applications are often compatible with 1A or 5A output current transformers. This class of CT was originally designed for use with electromagnetic meters. However, modern digital meters are frequently compatible with amperage-output current transformers as well. It is ideal for demanding industrial applications such as heavy manufacturing, production, or materials processing.
