Abstract: A pager-based controller including at least one pager configured to receive a signal from a remote location, the at least one pager being further configured to provide an output to change an on-off state of an external electrical component; a heater unit and a fan unit to maintain a predetermined temperatune range within the pager-based controller; a power supply for supplying a required AC voltage and DC voltage to electrical components within the pager-based controller; a latching relay electrically connected to the at least one pager; an interface unit electrically connected to the at least one pager and the latching relay, the interface unit configured to receive the output from the at least one pager and supply a corresponding signal to the latching relay; the latching relay including at least one normally-open contact and at least one normally-closed contact, for providing one of an open and a closed circuit to the external electrical component in response to an energization state of a coil within the l
Abstract: The present invention relates to an apparatus and method for distributing electrical power from power substation circuits. The apparatus of the present invention is responsive to overcurrent conditions and selectively actuates a switching network so as to restore power to at least a portion of the users connected to the faulty circuit of the power distribution system.
