About the Product

EOS-RN Series

Low-voltage window-type current transformers EOS-RN Series are resin-insulated instrument transformers designed to be used in indoor settings. In an EOS-RN current transformer, the window is sized at 33, 38, 60, 90, or 120 m/mψ. On the primary side, wiring can be done with a busbar or with insulated wire. The specifications of the EOS-RN Series allow a Primary Current of 100A~3200A and offer a Burden and Accuracy of 15~30VA/1.0CL. When used for billing purposes, and if the Primary Current is above 200A, the EOS-RN Series Current Transformers offer a Burden and Accuracy of 5~30VA/0.5CL. (however, if the Primary Current is under 100A, it is necessary to adjust the number of primary turns). Each of the EOS-RN Series Current Transformers comes with a sealable terminal cover for its secondary side. Fixed with a metal base and featuring a fine exterior, these compact-sized current transformers are characterized by their excellent physical and electrical properties.
