Fuses A single fuse is a two-terminal component that can be plugged or screwed into a compatible fuse slot. There are different types, which differ in their geometry, the type of connection, the tripping characteristics and their rated voltage.
In VEC a fuse is handled as a EE-Component and that is why the FuseSpecification extends the EEComponentSpecification and describes it’s the available connector interface also with a HousingComponent and - in this case - with two PinComponents.
