Schneider Electric's Square D 180R-401 current transformer provides a 400:5 current ratio, with a primary rating of 400 A and a 5 A secondary output. This makes it suitable for stepping down high currents to a 5 A signal for metering or protective-relay inputs in electrical distribution. As part of Schneider Electric's Square D line, the 180R-401 is designed for reliable current sensing in panelboards and switchgear applications.
