Abstract:
1. A system comprising: a first busbar; a second busbar; and a low-voltage power circuit breaker including a first contact arrangement for connecting a stationary contact to the first busbar, and a second contact arrangement for connecting an opposing contact, arranged on a contact lever, to the second busbar, each of the first and second busbars including at least one contact region by which the busbars are permanently arrangeable on a withdrawable part rack of the low-voltage power circuit breaker, each of the first and second busbars having a side which faces the low-voltage power circuit breaker, by which the busbars are permanently arrangeable on the outside of the low-voltage power circuit breaker, and each of the first and second busbars including at least one accommodating region for at least one retaining device by which the busbars are permanently lockable on the withdrawable part rack of the low-voltage power circuit breaker so as to form the low-voltage power circuit breaker as a withdrawable circuit breaker or on the outside of the low-voltage power circuit breaker so as to form the low-voltage power circuit breaker as a permanently installed circuit breaker, wherein the busbars are arrangeable on the withdrawable part rack when the low-voltage power circuit breaker is a withdrawable circuit breaker such that they have a same installation depth as the busbars when the low-voltage power circuit breaker is a permanently installed circuit breaker.
