Siemens Sirius 3UG5 Monitoring relay

digitally adjustable monitoring relay phase failure, phase sequence, asymmetry, frequency, over- and undervoltage monitoring 3x 90-690 V AC, 15-70 Hz 2 changeover contacts screw terminal Network monitoring relay with digital setting SIRIUS 3UG5 for monitoring phase sequence, phase failure and phase asymmetry, undervoltage and overvoltage as well as frequency, e.g. in case of unstable networks or with mobile systems such as A/C compressors, cooling containers, construction site compressors, cranes or solar systems and wind turbines. Use worldwide thanks to a wide voltage supply range and international certificates. The relay is variably adjustable for surplus, deficit or window monitoring. Delay times and RESET behavior can be freely set. Reduced space requirement in the control cabinet due to the slim design. Reliable diagnostics due to display of the current value and type of current system error. All versions with removable terminals. In addition to screw terminals, all devices are also available with spring-loaded terminals for quick, maintenance-free and vibration-proof connection. Automatic correction of the direction of rotation is available on request. A version with IO-Link is available for communication connection. In addition, devices with SILÂ 1/PLÂc certification are available. The comprehensive range of accessories, such as unit marking plates, spare terminals and sealing covers, is standardized for all relays. 3UG5 line monitoring relays replace the well-proven 3UG4 series. SIRIUS relays - a series for every application.
