ABSTRACT:
A low-voltage circuit breaker comprises a current transformer which at least partly encloses a first connecting bar and is supported by a stationary carrier independently of a second connecting bar. In the region opposite this support, the current transformer is disposed between an L-shaped carrier (angled-off), of the contact arrangements of the circuit breaker and an insulating piece inserted between the connecting bars. In this arrangement, the current transformer can be exchanged with a relatively small amount of labor, while at the same time, adequate strength of the connecting bars against forces is achieved which are introduced into the connecting bars by the continuing current bars.
