OPCT10ATL Split Core Current Transformer 1000/1 2000/1 3000/1 OPCT16ATL 4000/1 5000/1 Clamp CT 5A 20A 30A 50A 100A 150A (CT10ATL-60A 2000-1)

The OPCT10ATL and OPCT16ATL Split Core Current Transformers are precision-engineered clamp-style CTs designed for accurate and reliable AC current measurement in a wide range of electrical applications. Featuring a convenient split core design, these transformers can be installed quickly and easily around existing wiring without the need to interrupt or disconnect circuits. Available in multiple current ratio options — including 1000/1, 2000/1, 3000/1, 4000/1, and 5000/1 — they offer exceptional versatility to suit various measurement needs, with input current ranges spanning from 5A up to 150A. Built with copper windings, these transformers deliver stable and accurate readings. The OPCT10ATL features a 10mm aperture, while the OPCT16ATL offers a larger 16mm aperture to accommodate different wire sizes. Each unit comes with a 1-meter cable for convenient connectivity. Designed for single-phase applications, these transformers operate reliably across a wide temperature range of -22°F to +158°F and are constructed with flame-retardant UL94-V0 rated materials for added safety. The power frequency withstand voltage is rated at 2.5kV/1min, ensuring robust performance in demanding environments.
