Claims

[Scope of utility model registration request]

a first fixed contact; a first movable contact that separates from the first fixed contact when an overcurrent flows; and an arc-extinguishing plate for extinguishing an arc generated by the separation. a first opening/closing mechanism section having a second stationary contact;
A second movable contact that is in constant contact with the fixed contact and is separated by electromagnetic repulsion when a large current flows.
an opening/closing mechanism section, and a partition plate that partitions between the first and second opening/closing mechanism sections, and the first opening/closing mechanism section is provided in the upper part of the partition plate, and the second opening/closing mechanism part is provided in the lower part of the partition plate. At the same time, the first fixed contact, the movable contact, and the second
In a circuit breaker in which a fixed contact and a movable contact are connected in series, an opening/closing part of the first fixed contact and the movable contact, and an opening/closing part of the second fixed contact and the movable contact. A circuit breaker characterized in that a through hole is formed in the partition plate to communicate with each other.
