Time delay fuse keeps fingers safe

CUBEFuse improves system safety by maximizing component protection while minimizing arc flash energy. The fuse is finger safe because installation and replacement features provide added protection from accidental contact. Its white viewport goes black and stays that way when a circuit fault occurs. The rectangular construction optimizes mounting space. Cooper Bussman; www.cubefuse.com
