<P>PROBLEM TO BE SOLVED: To provide a plug-in breaker in which allowable current capacity can be increased without deteriorating the contact reliability with a conductive bar. <P>SOLUTION: This is the plug-in breaker which is composed of two voltage poles and one neutral pole and connected to three conductive bars arranged in three steps vertically, and has receiving blades 5-8 which are respectively inserted into and connected to the branching connection part of at least two conductive bars out of the three conductive bars. A plurality of the receiving blades 5-8 are installed respectively for each conductive bar to be connected, and the receiving blades connected to the same conductive bar are electrically connected. In this case, the receiving blades 6, 8 or 5, 7 of the identical pole are arranged in the horizontal row and the receiving blades 5, 6 and the receiving blades 7, 8 are arranged in the vertical row for the other pole. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
