Epoxy-Cast Window-Type Current Transformers for Indoor Application, 3kV
About the Product
Insulated with Araldite® epoxy resin and designed for indoor use, these window-type current transformers are suited for the main panel or motor control panel of a medium-voltage (≦ 3.6 kV) power system. Good for protection and appropriate for measuring and monitoring instruments, these current transformers are available in both 2-core and single-core models. The window-type design facilitates installation and wiring with a busbar or insulated cables, which decreases the occurrence rate of contact point failure. The CR-3S Series current transformers are characterized by a high degree of moisture resistance, as well as superior physical and electrical properties.
