1. An active sensing and switching device (20) for use in controlling current to a load, comprising a controller means (U1) for disconnecting the load from a power source by providing a switch-open control signal based on a signal indicating a sensed value of electrical current to the load, characterized in that the controller means (U1) determines a nominal value for the electrical current to the load based on monitoring over a period of time the signal indicating the sensed value of electrical current to the load.
