Passive triggering of a circuit breaker for electrical feeders of motor vehicles

摘要

The breaker has two connecting units (1, 3) that are connected with each other. A current path extends between the connecting units in a conducting state of the breaker. A pyrotechnical interrupting unit (5) is provided on one of the connecting units, and interrupts the connection between the connecting units. The interrupting unit is thermally activated with an aid of a joule effect that is generated by one of the connecting units. An independent claim is also included for a method for interrupting power with a circuit breaker.
