Ferraz/Shawmut Fuses

It is important to have a fast semiconductor fuse, such as these Ferraz/Shawmut fuses, in the battery circuit that feeds the controller. If there were to be some major problem with the Zilla or motor, a standard fuse or circuit breaker would not trip fast enough to protect the controller from excessive internal damage.
