COMBI-6 MULTI-CHANNEL EARTH LEAKAGE RELAY

COMBI 6 X52U...
The Multichannel earth leakage relays COMBI 6 have been designed for the monitoring and protection of up to 6 independent systems. A single instrument of 3 DIN modules 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.

EARTH LEAKAGE RELAYS WITH TCS (TRIP CIRCUIT SUPERVISION)

A new function is available for Earth Leakage relays Type B and Type A-F that allows to constantly monitor the efficiency of the circuit breaker Trip circuit when is made of a shunt release coil.

The alarm contact (TCS Alarm) will be as positive safety (normally energized) and will be released after the programmed activation time delay in the following situations:

- Lack of device auxiliary supply (no delay, device off)

- When ELR is operating in measuring mode, in case of shunt release coil connection fault or in case of lack of the relevant auxiliary supply

- When ELR is operating in tripping mode, if the contacts (COM, NO) of the Trip Relay are not closed.

When normal operating conditions are restored, the Alarm Contact will be energized again after a programmable release time delay (or in manual mode with Memory setting).

Check out the Ordering Code for this new function in the Data Sheet of each type.

Kit NANO multifunction meters with 3 Rogowski coils

Q52R3H - The kit is made of a multifunction analyzer and 3 Rogowski coils, the analyzer input does not require external integrators. It is suitable for use in three-phase three-wires or four-wires electrical systems, even with unbalanced loads and distorted waveforms, for the acquisition of all the main measurements, including power and energy both generated and consumed. Connection is simplified with RJ45 connectors. The system is suitable for retrofitting in existing installations and for laboratory use, but also an excellent solution for monitoring electrical networks in new installations.
