LINETRAXX® CTUB100 series
The CTUB100 series measuring current transformers are combinations of CTBC… measuring current transformer cores and CTUB10… electronic modules, which convert AC and DC currents into an evaluable measurement signal. The measurement signals can be evaluated using devices of the RCMA420/423, RCMS460/490 or EDS440/EDS441LAB series.
The measuring current transformers are connected to the respective devices via a 2- or 6-core cable. They can be used in DC, AC, and 3(N)AC systems.
The CTUB101-CTBCxx measuring current transformers are intended for connection to devices of the RCMA420/423 series and are supplied directly from the evaluator with the supply voltage DC ±12 V via the 6-core cable.
The CTUB102-CTBCxx measuring current transformers are intended for connection to an RCMS460/490. If the CTUB102-CTBCxx measuring current transformers are connected to an RCMS460/490 system, a DC 24 V power supply unit is required for the measuring current transformers, which is available as an accessory.
The CTUB104-CTBCxx measuring current transformers are intended for connection to an EDS440 or EDS441LAB. If the CTUB104-CTBCxx measuring current transformers are connected to such an insulation fault locator, a DC 24 V power supply unit is required for the measuring current transformers, which is available as an accessory.
The measuring current transformer cores of the CTBC20P…210P series feature an integrated magnetic shield and are suitable for applications with high load currents or inrush currents.
