Monitoring relay phase sequence monitoring 3x 160-690 V AC, 15-70 Hz 1 changeover contact

monitoring relay phase sequence monitoring 3x 160-690 V AC, 15-70 Hz 1 changeover contact screw terminal Line monitoring relay SIRIUS 3UG5 for monitoring phase sequence, phase failure and phase asymmetry, e.g. with mobile systems such as A/C compressors, refrigerated containers, construction site compressors, cranes or photovoltaic systems and wind turbines. Worldwide use thanks to international certificates. Less space required in the control cabinet thanks to slim design. 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. Versions with a wide voltage range and without auxiliary voltage can be used in any networks worldwide. 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.
