COMBI-6 MULTI-CHANNEL EARTH LEAKAGE RELAY
COMBI 6 X52U.. X72U.
The Multichannel earth leakage relays COMBI 6 have been designed for the monitoring and protection of up to 6 independent systems. A single instrument 3 DIN modules size or 72x72 size allows a considerable optimization of the overall dimensions and of the wiring connection procedures, thanks also to the presence of withdrawable terminals blocks for the connections. The 4 front keys allow immediate programming, further simplified by the copy/paste function available in the setting menu.A push button dedicated to the Scroll of the channels allows the selection of the input to be displayed, while in case of trip intervention, the display will automatically show the last tripped channel, and the relative LED will be ON.It is available in 3 versions: Type B only - Type AF only - Mixed B / AF with 5 different input combinations.

Sensor ø110mm for Type B Earth Leakage Relays
TDB110
TDB series sensors are able to measure AC and DC currents with a DC-10kHz bandwidth, and 1mA resolution. TDB sensors have an integrated degauss function with DC offset zeroing, which is by relay command. This function sets to zero the Dc current measuring errors (DC offset) caused by terrestral magnetic field, permanent magnets, DC coil, temperature drifts, mechanical shocks or vibrations. The measuring error of the RMS current (AC+DC) is proportional to the line current and it depends on the geometrical layout of the conductors passing through the sensor hole. It also depend on the distance and the geometrical layout of the nearby conductors passing outside the sensor hole. The IΔn setting <100mA will be possible only by centering the conductors and with controlled environment conditions (temperature, vibration, EMI).

45° ANNIVERSARY
We are happy to celebrate this important milestone together.
2025 will be a very important year as it marks the 45th year of FRER's activity and a thought of gratitude goes to all those who have characterized our history.
It has been 45 years of choices and changes, 45 years of commitment and satisfaction. However, we see this anniversary as a stage in the journey undertaken as many others are to be achieved, with the same commitment and tenacity that have motivated us since the beginning and that have allowed us to get to this point.
We thank all those who have contributed in these years to the growth of FRER so that it could be an international company, certain that this anniversary can become a new starting point.

DIN rail Active Energy meter, single-phase, direct 40A with RS485 output
The new Energy Meter C18WSL040MD3AI 1 din module meter with RS485 Modbus output.
Thanks to the front touch screen button it’s possible to set the parameters such as modbus addresses and display additional measurements: A, V, Ptot and Energy.
The FRER ETHERNET gateway allows you to connect up to 32 C18WS to an Ethernet network (using a single IP address). The integrated FRER mini WEB-SERVER, which can be consulted via any browser for Internet navigation, allows the display and recording, with automatic or manual start, of the measurements, which can then be downloaded in .csv format
