The revolutionary Bussmann^TM series Low-Peak^TM CUBEFuse^TM delivers the smallest footprint compared to any Class CC, J or RK fuse solution — requiring up to 70% less space when combined with its unique fuse holder or UL^® 98 Listed Compact Circuit Protector switch. Freeing up space is powerful. And the CUBEFuse does just that, while packing up to a 300 kA interrupting rating and enabling higher equipment short-circuit current rating (SCCR). Available from 1 to 400 amps.
