AC/DC sensitive measuring current transformers (type B)

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, RCMS410, RCMS425, RCMS460/490 or 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 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. Electronic module for conversion of the residual current signal from the measuring current transformer core for the connection...

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 RCM… evaluator. If, however, a larger measuring range is selected, the resolution deteriorates. CTUB102 with EDS441-LAB: Location current EDS441-LAB max. 25 mA. Adjust the measuring range on the measuring current transformer to this range. CTUB105: Measuring range 3 is fixed and cannot be changed. Setting measuring range (not possible with CTUB105) # Potentiometer setting Response value RCMA/RCMS Measuring range peak ** – The use of...

LINETRAXX® CTUB100 series ^BENDER Ordering details P = full magnetic shield The measuring current transformers of the CTUB10x series comply with the requirements of the standard DIN EN 45545-2.

Composition example of a measuring current transformer from the individual components Electronic module: CTUB101 Measuring current transformer core: Measuring current transformer:CTBC35 CTUB101-CTBC3512 * For connection to an evaluator, a complete measuring current transformer is required. Both components can be ordered separately as spare parts. All current-carrying cables must be routed through the measuring current transformer. Never route an existing protective conductor through the measuring current transformer. The primary conductors may only be bent from the specified minimum distance....
