A surge protective device (SPD) circuit system for providing overvoltage protection to an electrical power circuit includes a PCB assembly, an SPD module, and an SPD monitoring system. The PCB assembly selectively mountable on the PCB includes a PCB and a remote signal (RS) PCB contact on the PCB. The SPD module includes an overvoltage clamping element and an RS spring contact including an RS contact portion. When the SPD module is mounted on the PCB and the electrical power circuit is connected to the PCB: the PCB electrically connects the SPD module to the circuit and the overvoltage clamping element provides overvoltage protection to the circuit; the RS contact portion engages the RS PCB contact; the RS spring contact is elastically deflected and persistently loads the RS contact portion against the RS PCB contact; and the RS spring contact is electrically connected to the SPD monitoring system via the RS PCB contact.
