HRN-43/UNI

• Monitoring of 3-phase mains: voltage in 2 levels (undervoltage and overvoltage) in range 138-276 V (3x 400 V/230 V) or 280-480 V (3x 400 V)
• phase asymmetry (can be switched off )
• Function of the second relay (independent/parallel).
• HRN-43: for circuits 3x 400 V (without neutral).
• HRN-43N: for circuits 3x 400/230 V (with neutral).
• Galvanically separated supply voltage AC 400 V, AC 230 V, AC/DC 24 V.
