Magnetic actuator for circuit breaker type modular electrical apparatus, has magnetic yoke with magnetic core moving respectively between attraction and remote positions towards and from yoke base in presence and absence of current in coil
Magnetic actuator for circuit breaker type modular electrical apparatus, has magnetic yoke with magnetic core moving respectively between attraction and remote positions towards and from yoke base in presence and absence of current in coil
The actuator has a U-shaped magnetic yoke (2) whose base and lateral walls define a volume housing a magnetic core (3). The walls have bent ends (8, 9), and the core is surrounded by an induction coil. The core moves between a position of attraction towards the base when the coil is traversed by a current, and a position remote from the base in the absence of current. The core projects beyond the opening of the U in the remote position. An independent claim is also included for a circuit breaker type modular electrical apparatus including a magnetic actuator.
