Bender Linetraxx CTUB100 Series Quick 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 de-
vices are suitable for detecting fault currents with smooth
DC components. They consist of a CTBC... measuring cur-
rent transformer core and a CTUB10... electronic module,
which can be combined to suit the application. The meas-
uring current transformers can be used in DC, AC, and
3(N)AC systems. The measurement signal is evaluated us-
ing devices of the RCMA420/423, RCMS460/490, respec-
tively EDS440/441-LAB series, to which the measuring
current transformers are connected.
General safety instructions
Part of the device documentation in addition to this ma-
nual 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 es-
sential to follow the existing safety instructions.

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
