The link 26 and the flexible conductor connection portions 20 and 21 extend to each section, and arcs generated in the first section and the second section are less likely to enter the other sections. Therefore, the generated arc hardly causes metal droplets to adhere to the opening / closing mechanism unit 10 and the trip units 23a and 23b, so that the trip operation is unlikely to occur, and the insulation deterioration between the different poles is hard to occur.

Since the devices 23b are arranged in the same plane as described above, the thickness of the circuit breaker including the case 1 and the case 8 can be reduced.
