The Eaton Cutler-Hammer 9253C00H11 current transformer steps down high current in AC electrical circuits to a 5 A secondary for accurate metering and protection. With a 1600:5 A ratio, a primary current of up to 1600 A corresponds to a 5 A output, enabling standard 5 A meters and protection relays to monitor load and fault conditions. The device is rated for systems up to 600 V and is designed for use in electrical distribution equipment operating within that voltage class. As part of the Cutler-Hammer lineup, it provides isolation between the high-current primary conductor and the measurement circuitry while delivering a reliable current signal to monitoring instruments.
