Claims

[Scope of utility model registration request]

An arc extinguishing chamber formed in a U-shape by connecting two side walls with a connecting wall, an L-shaped terminal part, an L-shaped fixed contact part having a fixed contact at one end, and both of these parts. In a circuit breaker in which a fixed contact block consisting of connecting parts connected at positions orthogonal to each other is housed in a frame by overlapping a connecting wall and a piece of an L-shaped terminal part, the connecting wall and the fixed contact block are The arc-extinguishing chamber and the fixed contact stand are fixed to the frame by providing protrusions on each portion that contacts the frame, and inserting the protrusions into grooves provided in the frame to fix the arc extinguishing chamber and the fixed contact stand to the frame.
