PROBLEM TO BE SOLVED: To improve workability of a conductor against a zero-phase current transformer and enable a conductor of each polarity to surely insulate from each other. SOLUTION: An inter-pole insulation barrier 42 arranged inside the zero-phase current transformer 35 insulates each conductor plate 221 to 223 penetrating the transformer 35 from the other, so that there is no need of coating the conductor plate one by one, which prevents the conductor plates from getting thick and facilitates their penetration work into the zero-phase current transformer 35. Further, the conductor plates 221 to 223 can be made compact as a whole by being appropriately bent and folded, so that they can be easily arranged inside the ground fault interrupter.
