Abstract

A low-voltage circuit breaker includes a first contact arrangement, for connecting a fixed contact to a first busbar and a second contact arrangement, for connecting a counter contact, arranged on a contact lever, to a second busbar. A low-voltage circuit breaker is produced, which may be converted with minimal material complexity and little effort from a fixed switch into a modular switch, whereby the busbars of a low-voltage circuit breaker include moulded features such that the low-voltage circuit breaker may be embodied as both a fixed breaker and a modular breaker.
