Overview
Function
3UG46 21/3UG46 22 monitoring relays
The 3UG46 21/3UG46 22 current monitoring relay is supplied
with an auxiliary voltage of 24 V AC/DC or 24 to 240 V AC/DC
and performs overshoot, undershoot or window monitoring of
the current depending on how it is parameterized. The device is
equipped with a display and is parameterized using three
buttons.
The measuring range extends from 3 to 500 mA or 0.05 to 10 A.
The rms value of the current is measured. The threshold values
for overshoot or undershoot can be freely configured within this
range. If one of these threshold values is reached, the output
relay responds according to the set principle of operation as
soon as the tripping delay time I
the ON-delay time on
The hysteresis is adjustable from 0.1 to 250 mA or 0.01 to 5 A.
The device can be operated on the basis of either the open-
circuit or closed-circuit principle and with manual or auto RESET.
One output changeover contact is available as signaling
contact.

The relays monitor single-phase currents for overshoot and
undershoot against the set threshold. They differ with regard to
their measuring ranges and voltage types.
