An associative current interrupter system provides improved circuit protection and electrical safety. A test control unit (200) applies a regulated series of input voltage levels to the appliance (300) which is to be subsequently protected under a series of minimum and maximum load sequences. The resulting data series is logged and compressed into a format suitable for downloading into a programmable interrupter (100). A remote interface (217) is provided to allow device-specific data series to be input from alternative sources. When the appliance is connected in series with the interrupter (100), load current, line voltage, and time constraints are sampled and compared to the data series, thus providing a continuous solution to the determination of normal vs. abnormal currents. An output relay (103) provides a switching element and an internally accessible calibration port (111) allows monitoring combined non-linearities for correction during manufacture.
