<P>PROBLEM TO BE SOLVED: To provide a circuit breaker which can be used in a DC circuit with simple structure by reducing the number of wires to be connected. <P>SOLUTION: The circuit breaker comprises a movable contact 14 for opening/closing the main circuit, a movable contact 13 bonded to the movable contact 14, a fixed contact 12 arranged at a position facing the movable contact, a fixed contact 11 which supports the fixed contact, an extinguishing device 17 for extinguishing an arc generated between the contacts, an opening/closing mechanism 15 for opening/closing the movable contact, and a trip device 16 which opens the movable contact by detecting an overcurrent of the main circuit. One power supply side terminal 18 out of two poles and another load side terminal 19 corresponding to the power supply side terminal of two poles are connected by a connection conductor plate 20 composed of a conductive material and having a convex shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
