Relay for monitoring phase sequence and failure HRN-55, HRN-55N
replacement or HRN-51 and HRN -51N
relay monitors phase sequence and ailure, exceeding o monitored voltage in 3 phase main
HRN-55 - supply rom all phases, which means that unction o relay is applicable also i one phase ails
HRN-55N - supply L1-N, it means that relay also monitors break o neutral point
fxed delay T1 (500ms) and a djustable delay T2 (0.5-10s)
aulty state is indicated by LED and output contact o relay is OFF.

ay in 3-phase main monitors correct phase sequence and ailure o any phase. GreenD is permanently ON and indicates presence o power supply voltage. In case o phaseure or exceeding voltage level red LED fashes and relay breaks. When changing tolty state, time delay applies. Time delay setting is set by a potentiometer on ront
nel o the device. In case o incorrect phase sequence red LED shines permanently
d relay is open. In case supply voltage alls below 60% Un (OFF lower level)relaymediately opens with no delay and aulty state is indicated by red LED.N-55: thanks to supply orm all phases, this relay is able to stay operational alsone phase is out.N-55N -supply L1-N, means that relay monitor also ailure in neutral wire
