Relay for monitoring over / under voltage
in 3-phase mains
•
it serves to monitor voltage in a switchboard, protection of devices in 3-phase main
•
it monitors value of voltage in 3-phase main
•
relay doesn’t monitor phase sequence
•
it is possible to set upper and lower level independently
•
adjustable time delay eliminated short voltage peaks and failures in the main
•
the device is supplied from monitored voltage
•
faulty state is indicated by red LED and by breaking output relay contact
•
output contact 1x changeover / SPDT 8 A / 250 V AC1
•
in case supply voltage falls below 60 % Un (U
OFF
lower level) relay immediately
breaks with no delay
•
HRN-57
: supply from all phases, means that relay is functional also in case of
failure in one phase
•
HRN-57N
: supply L1, L2, L3-N, means that relay monitors also failure of neutral wire
•
1-MODULE, DIN rail mounting
