LINETRAXX® CTUB100 series AC/DC sensitive measuring current transformers (type B)

Open the catalog to page 1

AC/DC sensitive measuring current transformers (type B) Product description 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...

Variants A measuring current transformer always consists of a measuring current transformer core and an electronic module, which is required for signal conversion and can be connected to an evaluator. Each electronic module can be combined with all measuring current transformer cores. Electronic modules • CTUB101 Electronic module for conversion of the residual current signal from the measuring current transformer core for the connection to RCM devices via terminals S1 and S2, supply voltage DC ±12 V • CTUB102 Electronic module for conversion of the residual current signal from the...

Wiring diagram 24V GND Power supply unit (STEP-PS…) + surge protection device * The measuring range must be selected according to the response value I∆N set on the RCMS460 or RCMA420/423 evaluator. If, however, a larger measuring range is selected, the resolution deteriorates. For the CTUB104, a selection of the measuring range is not required. Setting measuring range (not required for CTUB104) # 1 Potentiometer setting Response value RCMA/RCMS I∆n ≤ 0.1 A Measuring range peak 0…900 mA ** – The use of a type 2 surge protection device (SPD) is mandatory due to possible impulse voltages and...
