ABSTRACT:
A polyphase circuit fuse condition indicating device includes three substantially identical circuits forming a Y-connection across each fuse through first and second leads. Each circuit has an indicator light and a switch with resistors in the leads. The respective circuits are interconnected through a lead having a resistance for each circuit so that an indication will be rendered without a load across the fuse.
