Main printed circuit board for a residual current device module. This board integrates the electronic control circuitry and the mechanically latched trip mechanism used in a Socket-outlet Residual Current Device (SRCD system). It comprises of a solenoid actuator, magnetic assembly, plunger, contact bridge, concentrator components, reset button, springs, and connection interfaces to the sensing PCB and external terminals. The PCB receives the fault signal from a sensing PCB and actuates the trip mechanism through the solenoid, mechanically opening the circuit contacts to disconnect.
