Abstract
A circuit breaker is shown which includes a plurality of fixed contacts and a plurality of corresponding movable contacts. An actuating shaft is operatively connected to and actuates the plurality of movable contacts to couple with/separate from the corresponding fixed contacts. A supporting device for the actuating shaft can be movably connected to a wall of the circuit breaker, and the actuating shaft can be operatively coupled to the supporting device to rotate around a rotation axis relative to the wall of the circuit breaker and the supporting device itself. The circuit breaker can include an adjustment device for adjusting at least the position of the actuating shaft relative to the wall.
Claims20
A circuit breaker comprising:
- a plurality of fixed contacts;
- a plurality of corresponding movable contacts;
- an actuating shaft which is operatively connected to and actuates the plurality of movable contacts between a first position in which each of the movable contacts are coupled with a corresponding fixed contact, and a second position in which each of the plurality of movable contacts are separated from the corresponding fixed contact;
- a supporting device for the actuating shaft, wherein the supporting device is movably connected to a wall of the circuit breaker, and wherein the actuating shaft is operatively coupled to the supporting device so as to rotate around a rotation axis relative to the wall and the supporting device;
- and
- an adjustment means for adjusting a position of the actuating shaft relative to the wall.
A circuit breaker comprising:
- a plurality of fixed contacts;
- a plurality of corresponding movable contacts;
- an actuating shaft which is operatively connected to and actuates the plurality of movable contacts between a first position in which each of the movable contacts are coupled with a corresponding fixed contact, and a second position in which each of the plurality of movable contacts are separated from the corresponding fixed contact;
- a supporting device for the actuating shaft, wherein the supporting device is movably connected to a wall of the circuit breaker, and wherein the actuating shaft is operatively coupled to the supporting device so as to rotate around a rotation axis relative to the wall and the supporting device;
- an adjustment means for adjusting a position of the actuating shaft relative to the wall;
- anti-rebound means configured to cooperate with the actuating shaft and prevent the movable contacts from bouncing back towards the fixed contacts when moving from the first position to the second position;
- and
- wherein the supporting device comprises:
- a pin which is hinged on one side to the wall;
- and
- a shaped mounting plate, the shaped mounting plate having a hole fitted with a bushing, which receives a portion of the actuating shaft.
