成る回路遮断器。 A contact inserted into the main circuit between the terminal board on the power supply side and the terminal board on the load side, to which terminal screws are screwed together, and a trip device that closes the contact while accumulating force in the direction of pulling the contacts apart. In a circuit breaker equipped with an abnormal current detection device that releases the above-mentioned force and operates a trip device to open the contact when an abnormal current flows in the main circuit, a plurality of terminal boards on the load side are provided. The circuit breaker is placed on a terminal block installed on the outer periphery of the circuit breaker body, and the terminal block has a partition wall that partitions adjacent terminal boards, and the terminal block is placed on one side of the partition wall in a manner that spans all the terminal boards on the load side. An insulating plate that is in contact with the terminal block is arranged so as to be substantially perpendicular to the terminal block and close the gap between the parts corresponding to each terminal board, and the surface of the insulating plate at both ends of the insulating plate that is opposite to the surface that contacts the partition wall is in contact with the stage. A section is formed on the inner circumferential surface of the circuit breaker main body, and a main circuit board that becomes a part of the main circuit is continuous with each terminal board on the load side, and a section is formed at the connection part with the terminal board on each main circuit board. A circuit breaker comprising a rising portion that abuts on a surface of an insulating plate opposite to the surface that abuts the partition wall.
