Digital monitoring relay current monitoring, 22.5 mm from 0.05-10 A AC/DC over- and undershoot AC/DC 24 to 240 V DC and AC 50 to 60 Hz Start-up and interference peak delay 0.1 to 20 s Hysteresis 0.01 to 5 A 1 changeover contact with or without error memory Screw connection Successor product for 3UG3522-1AL20, 3UG3522-1AG20 and 3UG3522-1AC48-0AA1 Digitally adjustable current monitoring relay SIRIUS 3UG4 for monitoring currents for over- and undershoot, e.g. to ensure the functionality of electrical consumers or for wire break monitoring. Worldwide use validated by international. The relay can be variably set to over-, undershoot 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 diagnostics through display of ACTUAL value and status messages. 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.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.
