A movable switch contact arrangement for a low-voltage circuit breaker has a contact lever holder for holding a plurality of contact levers. The contact lever holder includes a base body and additional bodies attachable thereto, as well as external mounting arms for rotatable mounting to open and close the circuit breaker. Contact lever holders of different widths can be produced by combining the base body with additional bodies of different types in order to adapt the circuit breaker to a desired rated current.
