Abstract

The circuit breaker has a short circuit triggering system e.g. magnetic triggering system such as anchor (18), interrupting current flow via the breaker during a short circuit. An overload triggering system e.g. bimetal element, interrupts the flow via the breaker during stable exceeding of a limit value. The short circuit triggering system is detachable such that the flow is interrupted only by the overload triggering system. The anchor has a plunger (20) that is movable by a coil (16), and a recess (24) in which a locking bar (26) is engaged to detach the short circuit triggering system.
