CZ Series

Compact Flying Lead Current Transformers for AC Current Sensing and Monitoring

About the CZ Series

Amgis’ CZ Series flying-lead current transformers deliver high current capacity and high output voltage in a compact, fully potted package. Equipped with flexible flying leads for fast, straightforward installation, the series is available in three standard configurations: CZ-0500, CZ-0750, and CZ-100. The CZ Series is purpose-built for 50 Hz AC current sensing and monitoring across a wide range of industrial, energy, and control system applications.

Benefits of CZ Series

The CZ Series combines a large-bore center aperture with dielectric isolation and a wide operating temperature range, making it equally at home on the factory floor and in demanding outdoor environments. Each transformer is fully potted for environmental protection, with easy mounting wherever your facility needs it.
