A device for limiting the inrush current component of a current provided by a supply to a load, the device including an impedance arranged between the supply and the load, a switch arranged to divert the current from the impedance, an inrush period timer connected to the supply and arranged to activate the switch after expiry of an inrush time period, the inrush time period being a time period beginning upon the supply becoming active such that current is available to be provided by the supply to the load and a reset circuit connected to the supply and the inrush period timer, the reset circuit arranged to deactivate the switch and reset the inrush period timer in response to the supply becoming inactive such that no current is available to be provided by the supply to the load.
