A breaker includes conductors, each including an elongated flat cut portion, cutting chambers arranged in correspondence with the cut portions, a single cutting member that includes blades to cut the cut portions in the cutting chambers, a gas generator that generates gas to move the cutting member toward the cut portions, and an arc attenuation portion located between the two cut portions that are adjacent to each other. The conductors are located between two devices. Each cut portion is cut to form two separated cutting ends and electrically disconnect the devices. The arc attenuation portion attenuates an arc generated between the two cutting ends of one of the two adjacent cut portions and the two cutting ends of the other cut portion. |

1. A breaker that electrically disconnects two devices of an electric circuit, the breaker comprising:
a plurality of conductors, each including an elongated flat cut portion, wherein the conductors are located between the devices, the cut portions are aligned in a widthwise direction of the cut portions, and each of the cut portions is cut to form two separated cutting ends and electrically disconnect the devices; cutting chambers respectively arranged in correspondence with the cut portions, wherein the cutting chambers are each located at one side of the corresponding cut portion in a thickness-wise direction of the cut portion; a gas generator located at a side of the cut portions opposite to the cutting chambers; a single cutting member located between the cut portions and the gas generator, wherein the cutting member includes blades, the number of which is the same as the cut portions, and the gas generator generates gas that moves the cutting member to cut the cut portions with the blades in the cutting chambers; and an arc attenuation portion located between the two cut portions that are adjacent to each other, wherein the arc attenuation portion is formed from an electrically insulative material, and the arc attenuation portion attenuates an arc generated between the two cutting ends of one of the two adjacent cut portions and the two cutting ends of the other cut portion. |
