The PZCT-02 Split Core Current Transformer is a reliable and precise solution for measuring AC current in energy monitoring applications. Designed with a split-core construction, it allows for non-invasive installation around existing conductors without the need to disconnect wiring, making it ideal for monitoring building electricity consumption. It supports a measuring range of 0 to 100A with a 1000/1 turns ratio and features an internal resistance of 10Ω for consistent performance. Compatible with AC 220V and 380V supply voltages, this transformer operates across a wide temperature range of -40°F to +185°F and handles working frequencies of 50Hz to 60Hz. The compact 1.85 x 1.22 x 1.14 inch body comes with a 7.87-inch lead wire for flexible placement. With an insulation resistance exceeding 1000MΩ and a flame resistance rating conforming to UL94-V0 grade standards, this unit is built for safe and dependable long-term use. Relative humidity tolerance up to 90% at 104°F ensures performance in demanding environments. A practical choice for electricians, engineers, and DIY electrical projects alike.
