It collides with a and engages at the constraint point 50 to prevent the handle 36 from further moving toward the open circuit position.
- the components operate close to each other near the position other than the position where the switching mechanism is restrained during the normal switching operation or trip operation. There is no. Further, as best shown in FIG. 1, the restraining portion is disposed at a position far from the molten material generating portion such as the arc extinguishing device 27, and the gap between the arc extinguishing device 27 and the restraining portion is also reduced. Since various mechanical components and partition walls are interposed in the, the melt generated during the shut-off operation is less likely to scatter and adhere to the restraint portion, and a stable opening and closing operation can be performed.

Movable contacts 24 open If the handle 36 is moved clockwise to the open side in a state where the handle is not turned on, the toggle spring (not shown) is extended, and the handle arm 35 is also rotated clockwise and moved toward the open position.
- the first restraining pin 43 fixed to the handle arm 35 becomes the second stop pin 41 of the stopper 41.
- the stopper 41 engages with the restraining portion 4 1b at the restraining point 5 5 and rotates the stopper 41 in the direction of arrow B about the shaft 42, so that the first restraining portion 4 1 a of the stopper 41 1 Collides with and engages with the second restraining pin 57 fixed to the lower link 28 to prevent the handle 36 from further moving toward the open position.
- 60 is a constraint point between the lower link 28 and the Storno, ° 41.
- the first restraining portion 41 a of the stopper 41 engages with the second restraining pin 57 fixed to the lower link 28 at the restraining point 60.
- the handle 36 can be prevented from moving to the open position, and in the case of mild welding, the first restraining portion 41 a engages the second restraining pin 57 to link the lower link. Since a large force acts to pull up the upper part 28 in FIG. 7 in FIG. 7, the operating force of the handle 36 can act to peel off the welding of the contacts 22 and 24.
- the restraining part is disposed at a position away from the melt generating part such as an arc extinguishing device, and various mechanical parts and partition walls are interposed between the melt generating part (arc extinguishing device) and the restraining part. Therefore, the melt generated at the time of the breaking operation is less likely to be scattered and adhered to the restraint portion, so that a stable opening / closing operation can be performed.
- a restraining member that engages between the handle arm and the movable contact side link of the toggle link mechanism to prevent the handle from moving to the open position is provided.
- the handle can be prevented from moving to the open position, and in the case of slight welding, the lower link can be pulled up, and the operating force of the handle can act to peel off the welding of the contact.
- the circuit breaker according to the present invention is useful as a circuit breaker for protecting various electric devices used in a distribution system.
