Overview
The 6 SHT-101 current transformer is a non-ANSI rated, window-type instrument transformer engineered for precision current measurement and signal conditioning in industrial automation and electrical systems. With a standard 100:5A primary-to-secondary ratio, this CT converts high primary currents into safely measurable 5A secondary signals suitable for analog instrumentation, power metering, and protective relaying circuits.
