Abstract

A low-voltage circuit breaker has a contact arrangement, a drive mechanism for actuating the contact arrangement , and an actuating shaft, which is used for transmitting a drive force from the drive mechanism to the contact arrangement. A bearing device for the actuating shaft has at least one bearing body, which is connected to a pole component accommodating the contact arrangement. Thus a unit is formed, which can be tested independently of the other components of the circuit breaker. In the case of multipole circuit breakers, a common actuating shaft is used for all contact arrangements and pole components, which is mounted approximately in the center of the main bearing body and near the ends of the auxiliary bearing bodies.
