Abstract: A surge protection apparatus includes a first surge protection device (10) having a number of first transient suppressing elements, a second surge protection device having a number of second transient suppressing elements, and a circuit coupled to the surge protection devices. The circuit has a number of display elements, wherein the circuit is structured to receive input signals from the first and second surge protection devices and (i) responsive to any one of the first transient suppressing elements failing, causes the number of display elements to provide a first indication indicating that at least one of the first transient suppressing elements has failed, and (ii) responsive to any one of the second transient suppressing elements failing, cause the number of display elements to provide a second indication indicating that at least one of the second transient suppressing elements has failed.
