An apparatus is disclosed for controlling an interconnect switch connecting a power source to a load. The apparatus comprises an interconnect switch control circuit connected to the interconnect switch for closing the interconnect switch upon an application of voltage from the power source. A voltage storage circuit stores a voltage related to a nominal operating voltage of the power source. A comparator is connected to the voltage storage circuit for comparing an instantaneous voltage of the power source relative to a nominal operating voltage of the power source. A timing circuit is connected to the comparator and the interconnect switch control circuit for opening the interconnect switch for a selected period of time after a reduction of the voltage of the power source. The apparatus is suitable for disconnecting electrical power to the load after an interruption and/or reduction of voltage of the power source.
