UL® Class CF Branch Circuit Time-Delay Solution - CUBEFuse™

Eaton-Bussmann’s branch circuit fuse with Class J electrical performance comes in a space-saving design

Image of Eaton-Bussmann UL® Class CF Branch Circuit Time-Delay Solution - CUBEFuse™Eaton- Bussmann's series Low-Peak™ CUBEFuse is a UL Class CF current-limiting, dual-element, time-delay branch circuit fuse with Class J electrical performance. Available in indicating and non-indicating versions, this finger-safe fuse has a very compact, space-saving size and is easily applied using the CUBEFuse holder (TCFH_N) or UL 98 Compact Circuit Protector switch (CCP2_CF).

Eaton's holders and switches have an amp rating rejection feature to help prevent over-fusing. The 30 A, 60 A, and 100 A switches and holders will hold any CUBEFuse up to its rating, while the 200 A and 400 A switches and 200 A, 225 A, and 400 A holders will hold any CUBEFuse 110 A and above up to its rating. There is easy selective coordination with any other Bussmann series Low-Peak Class CC, J, L, or RK1 fuse with a simple 2:1 amp ratio between upstream and downstream fuses.

Features
  • The smallest installed footprint of any UL Class CC, J, or R fuse solution
  • UL Class CF with Class J time-delay electrical performance
  • Available in indicating and non-indicating versions
  • The indicating version features local easyID™ open fuse technology for faster troubleshooting and reduced downtime
  • A faster response to damaging faults helps reduce destructive thermal and magnetic forces
  • True dual-element fuse construction with a minimum 10 seconds time delay at 500% of rating
  • Long time delay minimizes nuisance openings caused by temporary overloads and transient surges
  • Up to 300 kA interrupting rating safely interrupts virtually any fault
  • Robust cycling and inrush current withstand
  • Low let-through currents under fault conditions
  • Provides Type-2 “no damage” protection for IEC motor starters when properly sized
Ratings
  • Volts: 600 VAC / 300 VDC
  • Indicating: 6 A to 400 A / non-indicating: 1 A to 400 A
