Schneider Electric's Square D 350R-202 current transformer is a window-type instrument transformer designed for DS switchgear, featuring a 2000:5 current ratio and an operating range of 25–60 Hz. This device provides a 5 A secondary output proportional to the primary current, enabling safe, scaled current sensing within Square D DS-series gear. As part of Schneider Electric's broader instrument-transformer lineup, the 350R-202 exemplifies the company’s window-type CT design used in DS switchgear applications.
