Product Details

Analog monitoring relay Phase failure and sequence Adjustable undervoltage Asymmetry 20% fixed 3 x 160 to 690 V 50 to 60 Hz AC Hysteresis 5% fixed Delay time 0-20 s 2 change-over contacts screw terminal Successor product for 3UG3013-1B... Network monitoring relay with analog setting SIRIUS 3UG4 for monitoring phase sequence, phase failure and phase asymmetry and/or undervoltage, e.g. with mobile systems such as A/C compressors, refrigerated containers, construction site compressors or cranes. Worldwide use thanks to international certificates. Different versions enable application-related selection of products. 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-type 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. The comprehensive range of accessories, such as unit labeling plates, push-in lugs and cover caps, is standardized for all relays. SIRIUS relays - one range for every application.
