Abstract (en)

[origin: EP1732098A1] The present invention provides a circuit breaker including a fixed element 3 having a fixed contact point 2, a movable element 5 tilting in a state of being supported by a shaft 7 and having a movable contact point 4 which comes into and out of contact with the fixed contact point 2, and a shunt conductor 10 fixed at one end to a rear end side of the movable element 5 which is opposite from the movable contact point 4 with respect to the shaft 7 and connected at the other end with a terminal 9, and being configured in such a manner that an electromagnetic force generated by a current flowing in the shunt conductor 10 and a magnetic flux excited by the current acts on the movable element 5 so as to cause the movable contact point 4 toward the fixed contact point 2, wherein the length of the movable element 5 on the rear end side is set to a length at least twice a distance between the shaft 7 and the movable contact point 4 in the horizontal direction, and the one end of the shunt conductor 10 is fixed in contact with the rear end side of the movable element 5.
