Schneider Electric 170R-162 Current Transformer

Schneider Electric's Square D 170R-162 is a rectangular window current transformer designed for metering and protection in electrical power systems. It has a 1600:5 ratio (primary 1600 A, secondary 5 A), a 4.25 inch window opening, and a 600 V operating rating with a frequency range of 25–400 Hz. The CT clamps around a conductor or bus to provide a current signal for metering instruments or protection relays, suitable for panel or switchgear installations in industrial and commercial power distribution. This model is part of Schneider Electric's 170R family of instrument transformers, offering a fixed-ratio current measurement solution for high-current circuits.
