<p><P>PROBLEM TO BE SOLVED: To provide an earth leakage breaker in which a short-circuit accident is not caused even when a zero-phase-current transformer is installed at right beside an electric leakage detection substrate. <P>SOLUTION: An insulating wall 21 is installed integrally with an insulating member 20 which covers the outer boundary of the zero-phase-current transformer 15 mounted in a case 1, and an electric wire 19 which passes through the zero-phase-current transformer 15 is insulated. By this, the short-circuit accident can be prevented. If the insulating wall 21 is made to combine an engaging part of the case 1, positioning against the case 1 of the zero-phase- current transformer 15 is made easier, and an assembling workability can be enhanced. <P>COPYRIGHT: (C)2004,JPO</p> |
