Monitoring voltage relay HRN-43

DESCRIPTION

• Monitoring 3-phase mains:

a)    Voltage in 2 levels: overvoltage and undervoltage
b)    phase asymmetry
c)    phase sequence
d)    phase failure

• Function MEMORY – manual reset, “RESET” button on front pannel.
• Selectable function of 2nd relay (independent / parallel)
• Fixed T1(200ms) and adjustable T2 (0.1 – 10 s) delay to eliminate short voltage drops and peak.
• Monitoring relays in 2 variants:

HRN-43: for circuits 3x400 V (without neutral)
HRN-43N: for circuits 3x400/230 V (with neutral)

TECHNICAL PARAMETERS
