It plugs directly into standard ATO/ATC fuse blocks, protecting wiring harnesses in trucks, trailers, and other 12V electrical systems. The Type II modified reset design stays open while power is present and resets only after the ignition is turned off, making it ideal for power windows, seats, sunroof circuits, or anywhere a fuse replacement is inconvenient.
