Application and short description
The
UFR1002IP
mains decoupling relay monitors voltage and frequency in three-phase networks and
complies with the conditions for central network and system protection in accordance with VDE-AR-N
4105:2018-11 for feeding into the low-voltage network.
For feeding into the medium-voltage network in accordance with VDE-AR-N 4110:2018-11, the UFR1001E is
suitable as unit protection at the generating units and as intermediate decoupling protection.
The device has a dual-channel single fault safety design, thereby meeting the requirements of VDE-AR-N
4105:2018-11. The function of the connected switch is monitored. When monitoring is enabled, the device
does not switch on again if a switch-off error is detected.
Limit values for different applications are preset. They can be easily changed where permitted. If the rated
voltage is changed, the device automatically adjusts the preset limit values. The standby input allows a
remote shutdown, such as with a ripple-control receiver.
With a colour LCD display (German/English) and joystick, it is easy to operate.
Measured values and settings are clearly displayed.
Via the integrated IP interface, the device can be programmed, updates installed and
the alarm buffer read out. The real-time clock (with power reserve) thereby facilitates the
alarms’ traceability. In conjunction with the coupling device VG1200, a voltage of up to
1,200 V can be
monitored.
