Time-delay Low-Peak CUBEFuse

The revolutionary BussmannTM series Low-PeakTM CUBEFuseTM delivers the smallest footprint compared to any Class CC, J or RK solution — requiring up to 70% less space when combined with its unique fuse holder.

Further, the CUBEFuse delivers the smallest footprint compared to any Class J solution — requiring up to 51% less space when combined with its unique UL® 98 Listed Compact Circuit Protector.

Freeing up space is powerful. And the CUBEFuse does just that, while packing up to a 300 kA interrupting rating and enabling higher panel SCCR.

The UL Class CF finger-safe CUBEFuse is available in indicating and non-indicating versions, and features separate overload and short-circuit elements to provide time-delay to withstand harmless inrush currents to minimize nuisance openings.

Available in ratings from 1 to 100 amps, the CUBEFuse can be closely sized to load for superior protection. It also features industry-first plug-in capability for easier installation.

Features

• Integrates with the Bussmann series Compact Circuit Protector (cat. no. CCP2) or Bussmann series CUBEFuse holder to minimize panel space

• 1 to 100 amp fuses are utilized in Bussmann series Quik-Spec™ Coordination Panelboard (QSCP) for easy installation in the smallest fusible panelboard footprint

• Finger-safe fuse design minimizes exposure to live parts, reducing hazard to personnel

• Current-limiting Class J electrical characteristics minimize incident energy and reduces arc flash hazards

• Optional open fuse indication helps speed troubleshooting for reduced downtime

• Easy selective coordination using published amp rating ratio tables with upstream Bussmann series fuses or Eaton circuit breakers

The Bussmann series Low-Peak CUBEFuse helps you go big, by going small.
