Zusammenfassung:An electromagnetic actuator including a saturable magnetic shunt system. The shunt is associated with a coil of the actuator and allows channeling of a more or less large part of the flow according to current circulating in the product. In this way, when the actuator is used in a circuit breaker, the actuator allows the circuit breaker to be triggered from a short circuit as usual and also from overload caused by action of the shunt.
