Voltage monitoring relay in 3P with adjustable levels HRN-54
3 x 300-500 V
without NEUTRAL
EAN:
8595188137201 |
Code:
7498
DESCRIPTION
It serves to monitor voltage, phase failure and sequence in switchboards, protection of devices in 3-phase mains.
It is possible to set upper and lower level of monitoring voltage.
Adjustable time delay eliminates short voltage peaks and failures in the main.
In case supply voltage falls below 60 % Un (UOFF lower level) relay immediately opens without delay.
HRN-54
: supply from all phases which means that relay is functional also in case when one phase is faulty.
HRN-54N: supply L1, L2, L3-N, means that relay monitors also failure of neutral wire.
