3UG5618-1CR20
digitally adjustable monitoring relay phase failure, phase sequence, asymmetry, frequency, overvoltage and undervoltage monitoring, with/without N conductor with phase sequence correction 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, refrigerated containers, construction site compressors, cranes or photovoltaic systems and wind turbines. Worldwide use thanks to wide voltage supply range and international certificates. The relay is variably adjustable to overshoot, undershoot or window monitoring. Delay times and RESET behavior are freely parameterizable. Less space required in the control cabinet thanks to slim design. Reliable diagnostics due to display of the actual value and type of power system fault. All versions with removable terminals. In addition to screw terminals, all the devices are also available with spring-loaded terminals for fast, 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 SIL 1/PL c certification are available. The comprehensive range of accessories, such as unit labeling plates, spare terminals and sealing covers, is standardized for all relays. The 3UG5 line monitoring relays replace the well-proven 3UG4 series. SIRIUS relays - one range for every application.
