Current and Voltage Controls  
3 Phase-phase Max. and Min. Voltage Control  
Types S 172, SYY 165  
• Monitoring relay and 3-phased measur-  
ing relay for upper/lower phase-phase  
voltages control  
• Measures if all 3 phase-phase voltages are within  
set limits  
• Measures on own power supply  
• Operates irrespective of phase sequence  
• Upper and lower limits separately adjustable  
• Built-in adjustable timer function  
• Output: 10 A SPDT relay  
• Plug-in type module  
• S-housing  
• LED-indication for power supply and output ON  
• Power supply is the 3-phased measuring voltage
