General Electric 600T-401 current transformer from GE Instrument Transformers, with a 400:5 A primary-to-secondary ratio and a 600 V rating. The 400:5 A ratio converts high primary currents to a 5 A secondary signal, enabling accurate current measurement for metering and protection relays in electrical systems. This model is designed for installations that require a standard 5 A CT secondary and a 600 V service rating.
