Eaton Cutler-Hammer 189-010-10 Current Transformer

The Eaton Cutler-Hammer 189-010-10 Current Transformer is a 10:10A ratio device rated for up to 600V, designed to safely step down primary currents to a 10A secondary for precise measurement and monitoring in electrical systems. It supports metering and protection circuits by delivering a proportional secondary current to meters, relays, and instrumentation used in distribution panels and other equipment tasked with monitoring load, detecting faults, and triggering protective actions. The unit is listed in Good, Clean condition, indicating minimal wear and readiness for installation in typical 600V installations. With the 600V rating and 10:10A ratio, this CT remains compatible with standard low- to medium-voltage architectures and commonly used protection schemes that expect 10A input ranges. Part number 189-010-10 identifies the exact Eaton Cutler-Hammer transformer in catalogs, helping ensure you select the correct device for your current-sensing and protection needs.
