Abstract:
An electromagnetic actuator has a yoke for guiding a magnetic flux, and a holding plate attached to an actuating member, the holding plate and yoke forming a first magnetic circuit. Furthermore a magnetic flux generation device is provided for generating a magnetic flux in the first magnetic circuit. The magnetic flux generation device has an under voltage release coil electrically connected to an auxiliary voltage source representing the value of a voltage to be monitored.
