Bender LINETRAXX CTUB100 Series Instructions Manual

LINETRAXX® CTUB100 series
AC/DC sensitive measuring current transformers (type B)
Intended use
The AC/DC sensitive measuring current transformers
(type B) of the CTUB100 series convert system leakage
and fault currents into an evaluable measurement
signal. The devices are suitable for detecting fault
currents with smooth DC components. They consist
of a CTBC... measuring current transformer core and
a CTUB10... electronic module, which can be combined
to suit the application. The measuring current trans-
formers can be used in DC, AC, and 3(N)AC systems.
The measurement signal is evaluated using devices
of the RCMA4..., RCMS4..., RCMB4... or MRCDB4...
series, respectively EDS440/441-LAB series, to which
the measuring current transformers are connected.
General safety instructions
Part of the device documentation in addition to this
manual is the enclosed "Important safety instructions
for Bender products".
Installation, connection and commissioning are to
be carried out by electrically skilled persons only!
It is essential to follow the existing safety instructions.

* Only recommended for retrofit if an AN420 power supply unit is already
available. In this case, if the ready-made connecting cable CTX... is used, the
green plugs of the connecting cable (on the evaluator side) must be removed.

Device features
• Multicolour LED for operation, fault and status
messages
• Electronic module can be exchanged without
mechanical separation of the primary conductors
• Extension/retrofitting or modification of functio-
nalities possible in case of changed monitoring
requirements
• Insensitive to load currents due to full magnetic
shield, can be used for high short-term system-
related load currents (for CTBC...P only).
• Monitoring of the connection to the measuring
current transformer

Afterwards, the individual conductors must be crimped and connected to the
RCMS460/490 or the AN420. In this case, the conductor "T" is not used
