Screw Clamp Terminal Block Accessories
Jumpering System
The jumpering systems bus poten-
tials between terminal blocks, reduc-
ing wiring time. Adjacent blocks or
selective terminal blocks within an
assembly can be easily interconnect-
ed, leaving terminal clamps free for
wiring. Purchase complete assem-
blies, which are ready for installation,
or select individual components to
create custom or extra long jumpers.
Jumper ampacity is lower than the
rated current of the respective termi-
nal blocks, therefore, applied current
must not exceed the maximum cur-
rent value of the block. Internal
jumpers may be used in combination
with external jumpers to achieve
additional jumpering possibilities.

Internal Jumper Assemblies
Internal Jumper Assemblies consist of a
Current Bar, Shorting Sleeves and
screws. They install easily into the center
of the terminal block and connect to the
current bar. They are available as stan-
dard 2, 3, 4 or 10 pole assemblies and
are ready for immediate installation.
Insulated internal jumpers provide shock
protection when installed on terminal
block assemblies.

External Jumper
External Jumpers bus potentials
between terminal blocks, reducing
wiring time. Adjacent or selected
blocks within an assembly can be
easily interconnected. Jumper poles
may be removed for selective
jumpering. Jumpers are insulated
and available in 2, 3, 4 and 10 pole
versions. They are made of tin plated
brass/copper.

Current Bars
Current Bars are offered to create
custom jumper assemblies for
increased number of poles or custom
jumpers. Select the current bar with
the required number of poles, or field
cut them to the required length. They
are made of tin or nickel plated cop-
per or brass.

Shorting Sleeves & Screws
Shorting Sleeves & Screws ensure
reliable and mechanically safe elec-
trical connections between current
bars and the terminal block current
bars. One shorting sleeve is required
for each jumpered terminal. They are
made of nickel plated brass.
