ABSTRACT:
A circuit interrupter is secured to a mounting pan together with an insulative block in turn mounting a transverse array of fuse load terminals in individual, spaced alignment with associated interrupter load terminals. A differential current transformer is mounted to the pan with its window located in the space between the interrupter and fuse load terminals. Plural fuses extend through the transformer window with their opposed end terminals in respective electrical connection with associated interrupter and fuse load terminals, whereby the transformer monitors the vectorial sum of the phase currents flowing through the fuses.
