This is a crowbar circuit that is designed to trip at 15 or 16 volts.  The circuit is designed to operate with typical power supplies operating at 13.8 volts.

The full kit includes a circuit board with the surface mount components pre-populated, 2 Anderson PowerPole connectors, an automotive blade type fuse holder, a 3 pin header and jumper connector to select the trip voltage.  The kit also includes 2 pre-cut acrylic plates to protect and insulate the top and bottom of the PC board, and the necessary hardware to mount the plates to the board.

The plus and minus traces from input to output are copper planes.  The board can handle 15 amps continuous or up to 30 amps at a 50% duty cycle of 30 seconds on and 30 seconds off.
