PROBLEM TO BE SOLVED: To reduce risk of erroneous operation due to heat generated by high current.SOLUTION: A breaker device connects a plurality of breakers 30 in parallel using a conductive plate 31, which is a metal plate. The breaker 30 comprises: an external case 1; a fixed-contact metal plate 4 having a fixed contact 5 inside the external case 1; a movable-contact metal plate 6 having an elastic arm 6A with a movable contact 7 arranged opposite the fixed contact 5; a fixed-side connection terminal 42 connected to the fixed-contact metal plate 4 and projecting from the external case 1; and a movable-side connection terminal 41 connected to the movable-contact metal plate 6 and projecting from the external case 1. The conductive plate 31 comprises: a fixed-side conductive plate 31B connected to the fixed-side connection terminal 42; and a movable-side conductive plate 31A connected to the movable-side connection terminal 41. The movable-side connection terminal 41 and the movable-side conductive plate 31A make the metal plate not to fuse, and are electrically connected to each other in face contact directly or via the conductive metal plate. |
