CUBEFuse The revolutionary BussmannTM series Low-PeakTM CUBEFuseTM 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). Now, the CUBEFuse spans 1 to 400 amps.
In addition to having the smallest footprint of any Class CC, J or RK fuse solution, the Bussmann series LowPeak CUBEFuse is the only product included in the UL Class CF. It’s a current-limiting, dual-element, time-delay branch circuit fuse with Class J electrical performance. And it features industry-first plug-in capability for easier installation. The finger-safe CUBEFuse is available in both indicating and non-indicating versions, with the indicating version featuring easyIDTM open fuse technology for faster troubleshooting and reduced downtime. The CUBEFuse is easily applied with CUBEFuse holders, Compact Circuit Protector switches or the Compact Circuit Protector Base.
