Bussmann Low-Peak™ CUBEFuse™ TCF20 Current Limiting Inrush Current Withstand Time Delay Fuse, 20 A, 600 V AC/300 V DC, 100/300 kA Interrupt, Class: CF, Square Body

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). Available from 1 to 400 amps.

• The world's first finger safe power fuse system
• Smallest footprint of any class fuse including class J, CC, T and RK
• The indicating version features easyID™ open fuse technology for faster troubleshooting and reduced downtime
• Faster response to damaging faults to help reduce destructive thermal and magnetic forces
• True dual element fuse construction with a minimum of 10 s time delay at 500% of rating
• Long time delay minimizes nuisance circuit openings due to temporary overloads and transient surges
• High 300 kA interrupt rating safely interrupts virtually any fault
• No venting of arc or molten metal and gases during opening
• Robust cycling and inrush current withstand
• Low let through currents under fault conditions
• Provides type 2 "no damage" in protection for IEC® motors starters when properly sized
• Easy selective co-ordination with any other Bussmann series Low-Peak™ class CC, J, L or RK1 fuse with simple 2:1 amp ratio between upstream and downstream fuses
