PROBLEM TO BE SOLVED: To provide a noise filter adaptable to a circumstance of a power supply of each country by fully working out a power supply circuit of the noise filter such that an earth leakage breaker of the power supply circuit is deactivated due to a leakage current from Y-capacitors interposed between phases of power supply lines and ground. SOLUTION: The noise filter 1 is provided with X-capacitors connected between the phases of the power supply lines and the Y-capacitors interposed between the phases of the power supply lines and ground. A switch 5 freely opened/closed is interposed between a connecting point of the Y-capacitors and ground. COPYRIGHT: (C)2005,JPO&NCIPI
