Carlo Gavazzi Monitoring Relay Voltage 3-Phase Plug-In SYY165415

Carlo Gavazzi Monitoring Relay 3-Phase, Phase Max. and Min. Voltage Control, S Housing, Plug-In, SPDT, Supply: 415VAC.

3-phase monitoring plug-in relay for separate upper and lower voltage control. Often used where the generated electrical power is unstable (or incorrect) in order to secure the equipment. The S 172 features built-in time delay.

General Characteristics

• Monitoring relay and 3-phased measuring relay for upper/lower phase-phase voltages control

• 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
