Digital monitoring relay for 3-phase voltage with N conductor for IO-Link AC 50...60 Hz 3 x 160 to 690 V phase sequence, phase failure, phase asymmetry, undervoltage and overvoltage, hysteresis 1-20 V, mains stabilization time, tripping delay time 1 changeover contact, screw connection Digitally adjustable mains monitoring relay SIRIUS 3UG4 for monitoring phase sequence, phase failure and asymmetry as well as undervoltage and overvoltage, e.g. in unstable networks or mobile systems such as air conditioning compressors, refrigerated containers, construction site compressors or cranes. Worldwide use thanks to wide voltage supply and internationally validated. The relay can be variably set to over-, under- or window monitoring. Delay times and RESET behavior can be freely parameterized. Less space required in the control cabinet thanks to a narrow width. Reliable diagnosis through display of actual value and type of network error. All versions with removable connection terminals.In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free and vibration-proof connections. They are also available in different voltages, optionally with IO-Link or with automatic direction of rotation correction.The comprehensive range of accessories, such as device identification plates, push-in tabs and cover caps, is standardized for all relays.SIRIUS relays - a program for all occasions.
