insulation is applied between
the primary conductor and the current transducers. Schneider Electric assumes
no responsibility for damage of equipment or personal injury caused by
products operated on circuits above their published ratings.
Introduction
The CTRx Series of Rogowski flexible rope style current transducers (CTs) provide secondary AC voltage proportional to the primary (sensed) current. For use with EM35xxA, iEM35x5 and EM42xx Series power meters, the CTRx Series CTs provide a cost-effective means to transform electrical service amperages to a voltage compatible with monitoring equipment. The flexible core makes it easy to fit in tight enclosures. These products provide reinforced insulation between the sensed conductor and the output leads.
