Residual current monitoring modules
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 signalLINETRAXX MRCDB300 series:
AC/DC sensitive residual current monitoring modules for MRCDB applications
LINETRAXX RCMB300 series:
Measurement of DC and AC residual currents in earthed systems (TN and TT systems). Consisting of the RCMB301 evaluation electronics and a CTBC20(P)...210(P) series measuring current transformer core
Modular SensorPRO series
- Open interface RS485 with Modbus RTU
- Single-channel RCM type-B combined with converter
- Real Fire protection for operating sites at risk of fire
- Most accurate measurement up to 100 kHz
- Filter options for various applications
- Installation in machines, Frequency converters, distribution boards, etc.

Difference between RCMB300 and MRCDB300 series
The
MRCDB300 series is certified according to IEC
60947-2 Annex
M Edition 5 (2016-06) and is therefore suitable for personal protection in industrial environments and for fire protection in installations with >
63A rated current.
Only the use of an MRCDB300 module and a switching element with isolating The device combination fulfills the requirements for an MRCD protective device in accordance with DIN EN 60947-2 Annex M.
RCMs are usually intended for monitoring purposes and to support preventive maintenance Maintenance before a protective device switches off.
