3kV / 7kV Current Transformers (1-Core / 2-Core & Single-Ratio / Dual-Ratio Options)
Indoor MV Epoxy-Cast CT with Busbar Terminal
About the Product
Insulated with Araldite® epoxy resin and intended for the main panel or the motor control panel of a 3.6 or 7.2 kV power system, each of these current transformers for indoor usage has a busbar terminal and is designed to be used in conjunction with measuring or monitoring instruments, or with protective relays.
The two-core model CR-6S-80T is available with a primary current rating of 500～3000A. When offered with a rated primary current of 800A or above, this model has an added tap in the secondary winding and can be used as a dual-ratio CT.
These current transformers are moisture resistant and mechanically robust, while providing excellent electrical performance.
