The OPCT16ATL Split Core Current Transformer is a precision-engineered clamp sensor designed for accurate AC current measurement in a wide range of electrical monitoring applications. Its split core design allows for easy installation directly onto existing wiring without the need to disconnect any cables, saving time and reducing installation complexity. The transformer features a 16mm window size, accommodating a variety of conductor sizes, and is built with a toroidal copper winding construction for reliable, consistent performance even in demanding environments. With flexible current ratio options ranging from 5A to 100A and multiple output options including 2.5mA, 5mA, 25mA, 33.33mA, 40mA, 50mA, and 100mA, this single-phase transformer adapts to diverse monitoring needs. It operates across a wide temperature range of -40°F to 185°F and offers a compressive strength of 2kV/50Hz/1min. The unit supports a working voltage of 0.66/0.72kV and comes with a 1-year warranty for added peace of mind.
