Voltage monitoring relays in 3P with adjustable levels HRN-57N
3 x 172-287 V
with NEUTRAL
EAN:
8595188137249 |
Code:
7515
DESCRIPTION
It serves to monitor voltage in a switchboard, protection of devices in 3-phase main.
It monitors value of voltage in 3-phase main.
It is possible to set upper and lower level independently.
Adjustable time delay eliminated short voltage peaks and failures in the main.
Relay doesn’t monitor phase sequence.
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.
