ZIEHL industrie-elektronik, 74523 Schwäbisch Hall, Germany, +49 791 504-0, info@ziehl.de, www.ziehl.de Relays for 3-phase networks type PSSW1 monitor 3-phase networks for phase-sequence, asymmetry and over- and un- dervoltage. Applications: Monitoring of 3-pha- se-networks at heat pumps, compressors or at machines at building sites. Functions: Over- and undervoltage, adju- stable ± 2-20 % (common) Asymmetry adjustable 5-15% Phase loss Phase sequence Switching delay adjustable 0,1-12 s (for voltage and asymmetry) Bifrequential measuring input 50/60 Hz Displays:
