The OPCT16ATL Split Core Current Transformer is a precision-engineered clamp-style AC current sensor designed for reliable monitoring of alternating current in a wide range of electrical applications. Featuring a split core design, this transformer allows for easy installation directly onto existing wires without the need to disconnect them, saving time and reducing downtime during setup. The compact 16mm window opening accommodates standard AC cables and busbars with ease. Built with a toroidal copper winding construction, it delivers accurate and stable current sensing across a broad input range of 0 to 100A, with flexible output options including 2.5mA, 5mA, 25mA, 33.33mA, 40mA, 50mA, and 100mA to suit various monitoring requirements. Rated for single-phase AC use at working voltages up to 0.66/0.72kV, it withstands compressive strength testing at 2kV/50Hz for 1 minute. The unit operates reliably across a wide temperature range of -40°F to +185°F. Comes with a convenient lead wire for straightforward connection to metering or monitoring equipment.
