3kV / 7kV Current Transformers (1-Core / 2-Core & Single-Ratio / Dual-Ratio Options)

CR-3(6)S-T Series

Intended for the main panel or the motor control panel of a 3.6/7.2 kV power system and designed to be used with measuring or monitoring instruments, or with protective relays. Each CT has a busbar terminal. Insulated with Araldite® epoxy resin.

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.
