Abstract
To improve a wiring structure to minimize depth occupied by an assembly of terminal conductors while the components of the terminal conductors are used in common for three poles and four poles, in relation to load-side main circuit terminal conductors inserted in a zero-phase-sequence current transformer of an earth leakage breaker. This earth leakage breaker is composed by leading and wiring terminal conductors of respective poles arranged on a load-side terminal block of a body case by making them pierce an annual core of the zero-phase current transformer. In the earth leakage breaker, core piercing parts of the terminal conductors 2R, 2S and 2T of R, S and T phases are each bent and formed in a U-shaped form excluding the terminal conductor of the N phase corresponding to a neutral wire of a main circuit, and thereafter inserted in and arranged along the inner periphery of the annual core of the zero-phase current transformer 7; the terminal conductor 2N of the N phase is divided into two conductor components 2N-1a and 2N-1b; the divided conductor components are arranged by allotting them on the front and rear sides of the annular core and by shifting positions thereof to prevent them from overlapping wiring paths of the terminal conductors of the R, S and T phases; and thereafter connection ends 2N-2 thereof are made to abut on each other at the inside center position of the annular core and connected to each other by a fastening screw 10.
