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
