A low voltage three-phase integrated current transformer is provided to simplify an operation process by integrating three current transformers by one-body type three-phase current transformer. Three current transformers are respectively connected to three phases(R, S, T) of a watt-hour meter, and is integrated into one-body type three-phase current transformer. One-body type three-phase current transformer measures currents of three phases at the same time. A current of R phase is measured through 1S and 1L. A current of S phase is measured through 2S and 2L. A current of T phase is measured through 3S and 3L. One-body type three-phase current transformer reduces an operation time and an installation space, and reduces danger of an accident in a wire connection operation and a repair operation.
