Other than a traditional circuit breaker panel, does anyone use any devices for amp overload or low voltage protection on their boats?

My company has designed a modular device (self contained)that can be applied to anything with DC power that will manage both electrical overload conditions, as well as, low voltage and I am wondering if there is a market for it in the marine industry. It's currently a severe duty application that is completely waterproof (potted), and would be easy to apply to a boat. Any thoughts?

We have some patents on the technology, as we can apply this with a feedback loop to alert the user by a warning light, toggle switch, etc. and the amount of inputs is endless. It can protect both the battery, as well as, ancillary electrically driven equipment.

Just let me know if anyone has any thoughts. Thanks.
