Overview
The Sentran 5AS-1600A split-core current transformer is a precision instrument transformer designed for accurate current measurement in high-amperage industrial circuits. This split-core design allows installation around existing conductors without breaking circuit continuity, making it ideal for retrofit applications and maintenance without downtime. The transformer converts 1600A primary current to a standard 5A secondary output, compatible with protective relays, meters, and data acquisition systems.
Key Features
- Split-core construction for safe installation on live circuits
- 1600A input with 5A secondary output at rated current
- Accuracy class 0.5% and 1.0% options for measurement precision
