The PZCT-02 Split Core Current Transformer is a compact and reliable clip-on sensing device designed for measuring AC current in the 0-100A range, making it ideal for monitoring building electricity consumption. Its split-core design allows for easy installation directly onto existing wiring without the need to shut down your electrical system. Measuring just 1.85 x 1.22 x 1.14 inches, this mini transformer fits into tight spaces with ease, and comes with a 7.87-inch lead wire for flexible connection options. The unit features a high-accuracy analog output with an internal resistance of 10 ohms and a turns ratio of 1000:1, ensuring precise current readings. Built to last, it offers an insulation resistance of over 1,000 megaohms, withstands a dielectric strength of 1,000V for one minute, and meets UL94-V0 flame resistance standards for added safety. It operates reliably across a wide temperature range of -40°F to +185°F and supports working frequencies of 50Hz to 60Hz, making it suitable for a variety of electrical monitoring applications.
