Abstract
A current sensor assembly includes a housing; a plurality of shields which are accommodated inside the housing and open toward the top of the housing; a plurality of bus bars to which three-phase current is applied and which are arranged spaced apart from each other so as to go past the plurality of shields, respectively; and a current sensor unit which includes a printed circuit board and a plurality of current sensors disposed on the printed circuit board to measure the current applied to the bus bars. The shields, the bus bars, and the current sensor unit are configured to be accommodated inside the housing, and the current sensors are spaced apart from the bus bars and disposed in the inner spaces of the shields.
