Description
The Bussmann™ 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, UL
98 Compact Circuit Protector switch or Compact
Circuit Protector Base (CCPB — used in the Quik-
Spec™ Coordination Panelboard).

The finger-safe CUBEFuse in the 35 mm
DIN-Rail or panel-mount CUBEFuse holder
(TCFH_N). Holders are available in 30, 60 and
100 A ratings that dovetail together to create
the desired number of poles. Each holder will
accept a CUBEFuse amp rating up to the holder’s
amp rating (e.g. a 60 A holder will accept any
CUBEFuse up to 60 amps).

Features
•
•
Time-current characteristics — average melt
The world’s first finger-safe power fuse system
Smallest installed footprint of any UL Class J, RK or T fuse
solution
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
Faster response to damaging faults to help 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
High 300 kA interrupting 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” protection for IEC motor starters
when properly sized
Easy selective coordination 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.

UL Class CF branch circuit time-delay CUBEFuse
CUBEFuse holders, UL 98 disconnect switches and fusible
panelboards
The CUBEFuse is used in the following Bussmann series products:
CUBEFuse 30, 60 and 100 A 35
mm DIN-Rail or panel mounted
holders can be dovetail together
for the smallest footprint
possible of any Class J fuse
solution (see data sheet no
9007).
30 amp CUBEFuse holder
accepts any CUBEFuse up to
30 A.
The DIN-Rail mounted 1-, 2- and 3-pole Compact Circuit Protector
(CCP_CF) is a UL 98 horsepower rated disconnect switch available in
30, 60 and 100 A versions. Each CCP will accept a fuse amp rating
equal to or less than its rating (e.g., a 60 A CCP will accept any
CUBEFuse up to 60 A). Accessories include auxiliary contacts and
PLC fuse monitor (see data sheet no. 1157).
60 amp CUBEFuse holder
accepts any CUBEFuse up to
60 A.
100 amp CUBEFuse holder
accepts any CUBEFuse up to
100 A.
The 1-, 2- and 3-pole Compact Circuit Protector Base (CCPB) is a UL
98 horsepower rated branch circuit disconnect switches. Primarily
used in the Quik-Spec Coordination Panelboard, it’s available in
ratings up to 100 A. The CCPB has amp rejecting breaks at 15, 20,
30, 40, 50, 60, 70, 90 and 100 amps that coincide with standard
conductor ampacities and helps prevent overfusing by rejecting any
CUBEFuse amp rating greater than that of the switch.
