The OPCT16ATL Split Core Current Transformer is a precision clamp-style AC current sensor designed for easy installation on existing circuits without the need to disconnect any wiring. Featuring a split core design with a 16mm window opening, it can be quickly clamped around a conductor for non-intrusive current monitoring. Built with copper winding and a toroidal coil structure, this single-phase transformer delivers reliable and accurate current measurement across a wide range, from 5A up to 100A, with multiple secondary output options available. The unit operates at a working voltage of 0.66/0.72kV and has been tested to withstand 2kV compressive strength, ensuring robust performance in demanding environments. It is rated for an operating temperature range of -40°F to +185°F, making it suitable for both indoor and outdoor low-voltage AC applications. The transformer carries a current ratio of 1000/1 and is ideal for energy monitoring, power metering, and industrial control systems. It comes with a generous lead wire for flexible installation. Backed by a 1-year warranty.
