Coil actuator for a switching device and related switching device

摘要

A coil actuator for an associated switching device which can be actuated during its operation from an open position to a closed position so as to allow a current flowing therethrough and from the closed position to the open position so as to interrupt such current flowing. The 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 is suitable to cause the actuation of the switching device;
- electronic means arranged to count an operation time which is indicative of the duration of the actuation of the switching device.
