IEC—XB Series Overview
Product Description
The XB Series from Eaton
offers a complete terminal
block system with a universal
range of accessories.
Marking, bridging and testing
accessories are standardized
across the different
termination technologies—
reducing inventory and
logistics costs. The modular
terminal block design allows
for use of the different
terminal block types together
or individually, providing the
highest degree of flexibility.
Application Description
The metal portion of the XB
Series terminal blocks are
made from high-grade, strain-
crack and corrosion-proof
copper alloys. They won’t
experience any electrolytic
corrosion or rusting, even
when moisture is present.
The metal surfaces are
protected with a lead-free,
galvanic nickel or tin plating.
The good electrical
conductivity permits only a
low temperature rise. The
Polyamide 6.6 housings
allow for operating
temperatures up to 257°F
(125°C) and are certified for
inflammability Class V0 in
accordance with UL 94.
Features
Global acceptance—The XB
Series terminal blocks are
designed to worldwide
standards and meet the latest
international requirements.
Flexible Plug-in bridge
system—All three
technologies (screw, spring
and IDC) use the same bridge
system, allowing for
individual potential
distribution and quickly
bridged connections among
the same terminal block type
or across different types. The
XB Series terminal blocks
have two bridge shafts
arranged in one line, making
flexible chain bridging and
skip bridging between non-
adjacent terminal blocks
possible. Plug-in bridges are
available from 2 to 50
positions. Reducing bridges
are also available to connect a
larger terminal block to a
smaller one.
Large surface area for
marking—All XB Series
terminal blocks have
generously sized surface
areas for labeling. This allows
for clearly labeled wiring that
results in reduced startup
time and simplifies activities
such as testing and
maintenance. There are
provisions for marking
individual terminal blocks and
end stops, strips of terminal
blocks, and large groups of
terminal blocks.
Standardized testing
system—All test plugs make
contact in one of the easily
accessible bridge shafts. A
2.3 mm diameter test plug is
available for individual
measuring wires. Modular
test plugs are also available
for more advanced testing.
