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 (TCFH_N), UL
98 Compact Circuit Protector switch (CCP2-_CF)
or Compact Circuit Protector Base (CCP2B up
to 100 A) used in the Quik-Spec™ Coordination
Panelboard).

Dimensions — in (mm)
•
Smallest installed footprint of any UL Class CC, J, or R fuse
solution
•
Easy application using CUBEFuse holders (TCFH_N), UL 98
Compact Circuit Protector (CCP2) switches and Compact Circuit
Protector Base (CCP2B up to 100 A). See data sheet 9007 for

Up to 100 A
Holders and switches have an amp rating rejection feature to help
prevent overfusing; 30, 60 and 100 A switches and holders will
hold any CUBEFuse up to its rating, 200 and 400 A switches and
200, 225 and 400 A holders will hold any CUBEFuse 110 A and
above up to its rating

CUBEFuse (cat. no. TCFH_N) holders
The CUBEFuse is used in holders that can be dovetail together for
the smallest footprint possible of any Class J fuse solution (see data
sheet no. 9007 for details).
Finger-safe DIN-Rail or panel
mount holders up to 100 A.
•
30 A holder accepts any
CUBEFuse up to 30 A.
•
60 amp holder accepts any
CUBEFuse up to 60 A.
•
100 amp holder accepts any
CUBEFuse up to 100 A.
Panel mount holders from
200 to 400 A.
•
200 A holder accepts any
CUBEFuse from 110 to 200 A
•
225 A* holder accepts any
CUBEFuse from 110 to 225 A
•
400 A holder accepts any
CUBEFuse from 110 to 400 A
200 and 400 A Compact Circuit Protector (cat. no. CCP2-CF)
switches
These panel mounted 1-, 2and 3-pole switches are UL 98
horsepower rated disconnects.
Each CCP2 will accept a fuse
amp rating equal to or less than
its rating (e.g., a 200 A CCP will
accept any CUBEFuse from 110
to 200 A). Complete installation
requires installing various
lugs to meet the application
requirement. Accessories
include side or front rotary
operators and auxiliary contacts
(see data sheet no. 10801 for
details).
Compact Circuit Protector Base (cat. no. CCP2B)
These 1-, 2- and 3-pole switches
are UL 98 horsepower rated
branch circuit disconnects.
Primarily used in the Quik-Spec
Coordination Panelboard, they’re
available in ratings up to 100 A.
The CCP2B has amp rejection
breaks that prevent installing
any CUBEFuse amp rating
greater than that of the switch.
These coincide with standard
conductor ampacities to help
prevent overfusing and are
available at 15, 20, 30, 40, 50,
60, 70, 90 and 100 amps for all
1-, 2- and 3-pole switches.
Finger-safe installation
achievable for three ganged
holders and lug kits with shroud
* 200 A and 225 A holders share the
same overall dimensions, but the
200 A holder will reject a 225 A fuse.
30, 60 and 100 A Compact Circuit Protector (cat. no.CCP2_CF)
switches
These DIN-Rail mounted 1-, 2and 3-pole switches are UL 98
horsepower rated disconnects
available with front or side
rotary operators. Each CCP2
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 multi-wire
lug kits with shrouds, auxiliary
contacts and PLC fuse monitor
(see data sheet no. 10801 for
details).
