Bussmann CUBEFuse® TCF30 Indicating Non-Rejection Time Delay Fuse, 30 A, 600 V AC/300 V DC, 100/300 kA Interrupt, Class: CF, Square Blade 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.

• Worlds first finger safe power fuse system
• Smallest footprint of any class fuse including class J, CC, T and RK
• Meets class CF and class J time delay electrical performance requirements
• 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
• Long time delay minimizes nuisance circuit openings due to temporary overloads and transient surges
• High interrupting rating to safely interrupt faults up to 300 kA
• 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 coordination with any other Cooper Bussmann low peak class CC, L, J and RK1 fuse with simple 2:1 amp ration between upstream and downstream fuses
• -40 to 80 deg C operating temperature
• 300 kA RMS symmetrical (UL) and 300 kA RMS symmetrical (CSA) at 600 VAC, 100 kA (UL and CSA) at 300 VDC interrupt rating
• Copper alloy terminals, electroless tin terminal plating, PES (polyethersulfone) indicator lens, energetic chemical indicator
• 10 sec at 500% response time
