ORDERING INFORMATION
Distribution Block
Example Part No.
Splicer Block
Example Part No.
POWR-BLOKS power distribution blocks offer a safe, conve-
nient way of splicing cables, providing a fixed junction tap-off
point or splitting primary power into secondary circuits.
LX2XXX-DIN series offers integral DIN-Rail mount and an
optional hinged safety cover.
APPLICATIONS
Typical applications include heating, air conditioning and
refrigeration systems, elevator systems, material handling
equipment, control panels, motor controls, switchgear, and
anywhere power needs to be distributed to more than one load.
AMPERE RATINGS
The ampere rating per pole for power distribution blocks is
based on the line ampacity of 75° C insulated conductors per
NEC Table 310.16. If 60° C insulated conductors are used,
load must not exceed the ampacity of 60° C conductors. Use
of conductors rated in excess of 75° C is permitted (for
example 90° C), however, load must not exceed the
ampacity of 75° C conductors.
CONNECTORS
Box lug connectors are designed for use with a single, solid or
class B or C stranded conductor. Use of more than one conductor
per connector opening or use of extra-flexible, fine stranded
conductors, such as welding cable, voids the UL Listing, and may
cause overheating. Manufacturers of cable terminations can
furnish crimp-on sleeves for fine stranded conductors which permit
these conductors to be used with box lugs.

Littelfuse’s power distribution block covers provide protection
against accidental shorting between poles caused by loose
wires, tools, or other conductive material. They also protect
personnel from accidentally contacting energized connec-
tors. Clear plastic covers are available for most blocks. New
LX2XXX-DIN series blocks offer a hinged cover.
