Abstract

A circuit breaker (100) includes a housing (10) having a first cavity (11) and an arc-extinguishing chamber (12). A moving contact support (21) has a pivot axis and a rotating arm (212). The rotating arm (212) can rotate in the first cavity (11) and is provided with a moving contact point (2121). A fixed contact (30) is disposed on the housing (10) and a second end (302) of the fixed contact (30) extends to a first side of the arc-extinguishing chamber (12). The fixed contact (30) is provided with a fixed contact point (33). An arc-extinguishing grid sheet assembly (40) is disposed in the arc-extinguishing chamber (12) and includes first and second arc-extinguishing grid sheets (41, 42) respectively corresponding to the first and second sides of the arc-extinguishing chamber (12). The arc-extinguishing chamber (12) extends in an arcuate shape. A distance (L) between a side surface (121) of the arc-extinguishing chamber (12) facing towards the pivot axis and the pivot axis gradually increases in a direction from the first side to the second side of the arc-extinguishing chamber (12).
