Schneider Electric 74RFT162001 Current Transformer

Schneider Electric's Square D 74RFT162001 is a window-type current transformer (torroidal) designed for accurate current measurement in industrial distribution equipment. It features a primary-to-secondary ratio of 1600:1, enabling high primary currents to be scaled down to a 1 A secondary signal for metering, relays, or protective circuits. Built for rugged environments, it is rated for up to 600 VAC and offers a dielectric withstand of 10 kV, providing a generous insulation margin in panelboards and switchgear. The 74RFT family, including the 64R and 74R series, comprises single-ratio CTs with rectangular window designs that allow easy installation around a conductor without disconnecting the circuit. The model 74RFT162001 is suited for installations where a 1600:1 ratio is required, delivering dependable performance at standard 50/60 Hz power and compatible with common metering and protection devices. Typical applications include monitoring and protection in electrical distribution panels, motor control centers, and switchgear assemblies where safe, compact current sensing is essential.
