The Square D by Schneider Electric 2NR750 is a general‑purpose window‑type current transformer with a 75:5 current ratio, designed to monitor primary currents up to 75 A with a 5 A secondary. Its 1-1/8 inch (ID) window accommodates a single conductor and it is rated for up to 600 V AC, making it compatible with common industrial electrical distribution setups. At 60 Hz, it presents about 1.5 VA burden and delivers 2% accuracy at rated current, per Schneider Electric's catalog data for the 75:5 family.
