Class CC Blocks
Class CD Blocks
Space-saving 600 volt, 30 amp molded-case fuse blocks
with side barriers for isolation. Class CC blocks and Midget
blocks are identical except Class CC blocks incorporate a
rejection feature to assure proper fusing.
Rejection feature -- Class CC fuse blocks have a
rejection feature which prevents the insertion of fuses
with lower interrupting rating or voltage ratings. Class CC
fuses are rated 600 volts and have an interrupting rating of
200,000 amperes. Midget fuse voltage ratings vary
and their interrupting rating may be as low as 10,000
amperes. Note that Class CC fuses may be used in
Midget fuse blocks, but Midget fuses cannot be used
in Class CC blocks.
High-strength materials -- Class CC and Midget fuse
blocks are molded of high-strength, high-temperature
material to minimize block breakage during handling and
installation, as well as damage due to heat.
Reduced resistance, less heat -- High conductivity,
one-piece copper alloy fuse clips have lower resistance
than traditional two-piece brass or phosphor bronze fuse
clips . . . minimizes heat rise and watts loss within the
Gangable -- Interlocking fuse blocks allow ganging to
produce a fuse block with any number of poles.
Flexible terminal arrangements -- 30A Class CC and
Midget fuse blocks are available with type C box lug,
type SQ screw, or type PQ pressure plate terminals.
Type SQ terminals have binding-head screws, while
type PQ terminals have captive pressure plates.
Both terminal types can accommodate side- or top-
mounted quick-connect terminals. This flexibility allows
the accommodation of most needs and reduces part
60A CC fuse blocks are available with type C box lug
DIN rail mountable -- FBDIN1 adapters permit snap-
mounting Littelfuse Class CC and Midget 30 amp fuse
blocks directly to standard or low profile 35mm symmetrical
"hat" and 32mm asymmetrical DIN rails. Patented DIN rail
adapters snap securely to Littelfuse fuse blocks and to DIN
rails without tools. They can be readily removed from rails
by lifting the disconnect tab.
L60060C 60A fuse blocks have patented integral DIN rail
adapters which allow direct mounting to 35mm "hat" type
