An over-current electronic protection system includes a first solid state reversibly interruptible electronic switch including first output control logic and first controlled output channels controlled by the first control logic. The first output control logic reversibly interrupts power at any output channel when their current exceed limits. The system includes a second solid state reversibly interruptible electronic switch including second control logic and second controlled outputs. A power supply input of the second switch is coupled to one of the first controlled output channels to receive the power. The second controlled outputs provide power to loads under normal operating conditions and reversibly interrupt the power for second output channels when their current exceeds limits. A CPU having is coupled to the second output channels and external inputs of the second switches via an isolation device to provide a supervisory and monitoring function.
