Abstract
An exemplary coil actuator for an associated switching device which can be actuated during its operation from an open position to a closed position to allow a current to flow therethrough and from the closed position to the open position to interrupt such flowing from flowing therethrough. The coil actuator includes a coil electromagnet arranged to move between a rest position and an actuating position, wherein movement from the rest position to the actuating position is suitable to cause the actuation of the switching device; and an electronic component arranged to count an operation time which is indicative of the duration of the actuation of the switching device.

A coil actuator for an associated current switching device which can be actuated during its operation from an open position to a closed position to allow a current flowing therethrough and from said closed position to said open position to interrupt such flowing current, said coil actuator comprising:
- a coil electromagnet arranged to move between a rest position and an actuating position, wherein the movement from the rest position to the actuating position causes the actuation of said switching device,
- wherein said coil actuator includes electronic means arranged to count an operation time (Topen, Tclose) which is indicative of the duration of said actuation of the switching device.
