The Overload Protection used on CMPs varied but in general, they can not be called circuit breakers or fuses. They are a current regulator and they either work or they don’t. If you over load (short) the system the unit sit there and vibrate limiting the current flow to 25-30 amps hopefully low enough that a fire doesn’t start. The one on my HUP functions great. Before I put in the new wiring harness the old one shorted out and you could hear the limiter buz like a door buzzer. On the C60 the unit was fried and I replace it with a 30 amp automotive thermal circuit. It has only activated once when a wire came loose and shorted out behind the dash. Of course it was at night and the headlights went out.
