Large Surface Area for Marking—
All XB Series terminal blocks have
generously sized surface areas for labeling.
This allows for clearly labeled wiring which
results in reduced start-up 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.
TERMINAL BLOCKS
OVERVIEW
All models shown smaller
than actual size.
Product Family Overview
The XB Series offers a complete terminal
block system with a universal range of
accessories. Marking, bridging and testing
accessories are standardized across the
different clamping 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 highgrade,
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 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 meet
worldwide standards and the latest
international requirements.
Flexible Plug-In Bridge System—
All 3 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
2 bridge shafts arranged in 1 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.

Modular Terminal Blocks for
Potentially Explosive Environments
The standard modular terminal blocks
are approved for potentially explosive
environments. In addition to the usual
approvals, they also have been approved by
a testing center authorized by the EU.
No extra approval is required in intrinsic
safety type applications. Modular terminal
blocks on the internet address listed below
fulfill the requirements for “increased safety”
protection type when installation instructions
are followed, and have a type examination
certificate in accordance with the Ex
directive Ex-RL 94/9/EU. These test
certificates are recognized in all the EU
member states and beyond.
The modular terminal blocks are approved
for fitting in Zone 1, the Ex environment, as
well as Zone 2. Zone 1 fitting is conditional
upon terminal blocks being used in
connection boxes approved for EEx e type
protection and having the equivalent of at
least IP54 protection.
The EEx approved modular terminal blocks
can be divided into the following groups:
Screw connection terminal blocks
Spring-cage connection terminal blocks
Insulation displacement connection
terminal blocks
Mini terminal blocks
Terminal blocks for specialized
applications

The XBUT Series utilizes a screw connection
system that is accepted worldwide and is
suitable in most applications.
The maintenance-free connection
provides the reliability you expect.
Designed for applications with high
demands, the XBUT Series screw terminal
block has a maintenance-free wire
connection. Tightening of the terminal
screws is not necessary to ensure proper
operation. The screw locking technique
prevents the screws from backing out.
Copper wires can be clamped without
pre-treatment or ferrules can be used for
splicing protection. Multiple conductors
can be connected in the same clamping
mechanism, saving space.
The XBUT terminal blocks feature a
compact design and maintenance-free
screw connection. There is a double bridge
shaft providing maximum flexibility. The
double bridge shaft can accommodate
individual chain bridging and step down
bridging from other terminal blocks. There
are numerous options for accessories,
including those for testing and marking.
Terminal blocks are available for wire
cross-sections ranging from 12 AWG
(2.5 mm
2
) to 0 AWG (150 mm2).
