Abstract

The circuit breaker has at least one fault current sensor (1,2), a primary trigger system with a magnetic trigger (3), a secondary trigger system operating independently of the primary system and using a different technology, a contact arrangement (7) in a single or two-phase circuit and a contact arrangement drive system (6,18) activated by one or other trigger system if a fault current is detected. A mechanical force amplifier is arranged after the magnetic trigger and/or the drive system has two independently operating drives each preferably in the form of a switching lock.
