Product Overview

The YuanXing CTSR Series Split Core Current Transformers provide high-precision energy monitoring for industrial applications. These UL2808 and CAN/CSA-C22.2 compliant sensors feature a 600V AC rating and 2500V dielectric strength. Designed for power management and building automation, they support ratios up to 3000:1 with 0.5 accuracy class performance. They feature low cost, 50/60Hz frequency, 600V AC rating, and -40°C to +55°C operating range, ideal for power management, building automation, and motor monitoring. The easy-install split-core design facilitates retrofitting in electric motors.
