The CT-100 current split-core transducer features a built-in dip switch current range and measures up to 100A of current in selectable ranges of 0 to 2.5A, 0 to 10A, 0 to 20A, 0 to 50A, or 0 to 100A. The unit is capable of low output of 4mA and a high output of 20mA when connected to a controller or monitoring device. It is accurate to 2% at full scale and is designed to handle most applications of submetering and monitoring that consume less than 100A.
