The present invention relates to a current transformer for air circuit breaker which is capable of minimizing the volume and weight as well as measuring load conditions of a line and generating power at the same time, and improving a range of overcurrent characteristics. The current transformer for air circuit breaker according to the present invention comprises: a housing having an accommodating portion therein; a core coil built in the housing to generate power; a Rogowski coil built in the housing to measure load conditions; a printed circuit board built in the housing to purify radio waves; and a molding coupled to the top of the housing to block the opening of the accommodating portion in the housing, wherein the core coil has a right-angled bending section between both ends, and the bending sections diagonally face to each other to be coupled to each other in a form of a rectangular frame. |
