This is an exciting new departure from the traditional control transformer in that it is modular, has encapsulated windings and can be easily made into a finger safe CE approved transformer. The Century series comes with secondary fuse clips on every unit that can either be installed or discarded if not needed. In addition we offer this series with factory installed primary fuse kits. All of the kits can also be "dressed up" to be totally finger safe as well with the addition of special fuse covers
