The moving contact unit ( 10 ) is intended for a contact arrangement in a circuit breaker and contains a contact mount ( 13 ) and a contact piece ( 11, 111, 112 ), which is held by the contact mount ( 13 ). The contact mount ( 13 ) is arranged on a pivoting shaft ( 12 ), which can be mounted in the switch, and is fitted with a catch ( 135 ) which can pivot, and with a tripping lever ( 14 ) which can pivot and, together with the catch ( 135 ), forms a latching point. A simple configuration for the contact unit and for the contact arrangement which holds this contact unit is made possible, despite stringent requirements for maintenance of the circuit breaker and despite a high disconnection rating in that the tripping lever ( 14 ) is also arranged on the pivoting shaft ( 12 ) alongside the contact mount ( 13 ), and in that the contact piece ( 11 ) is placed on the contact mount ( 13 ) and is held by at least one prestressed bending spring ( 51 ), which is mounted on the pivoting shaft ( 12 ).
