An automated AC line filter and surge suppression apparatus 100 having an inductive current sense loop (ICSL) circuit 10 for sensing inductive current at a load and controlling the application of AC line filter 112 to an AC power line to the load. Current sensor 12 in series with the input line senses inductive load current. A first bridge rectifier 14 rectifies the sensed load current to a proportionate DC voltage, which triggers a switch 24. The output of switch 24 is fed into an opto-isolator 26, which in turn controls second switch 28. Switch 28 connects or disconnects AC line filter 112 from the system according to a predetermined sensed inductive current at the load. MOVs 102 and capacitive elements 104 provide continuous surge suppression protection to the load.
