ABSTRACT:
A low-voltage circuit breaker of compact design has a housing of insulating material with several parallel disposed chambers. A switching mechanism designed as a structural unit is provided in one of the chambers. The other chambers comprise compartments for switching path contacts. The switching mechanism comprises a U-shaped carrier for all moving parts. In particular, a drive shaft with a coupling part, such as a key, as well as a tripping shaft, likewise having a coupling part such as a slot, are provided. A pole control shaft is provided for actuating the switch contacts and is provided at its end with a coupling part such as a slot which comes into engagement with the coupling part of the drive shaft of the switching mechanism if the latter is built into the switch gear.
