Siemens 3UG5618-1CR20 3UG56181CR20 Network monitor No. of relay outputs: 2

Digitally adjustable monitoring relay Phase failure, phase sequence, asymmetry, frequency, over and undervoltage monitoring with phase sequence correction 3x 90-690 V AC, 15-70 Hz 2 changeover contact screw connection Digitally adjustable mains monitoring relay SIRIUS 3UG5 for monitoring phase sequence, failure and asymmetry, under and overvoltage as well as frequency, for example in unstable networks or mobile plants like air-conditioning compressors, cool containers, Construction site compressors, cranes, and solar and wind power plants.Worldwide use through wide-voltage supply and international certificates. The relay can be set to over-voltage, under-voltage or window monitoring. Delay times and RESET response can be freely parameterized. Small width means less space in a control cabinet. Reliable diagnostics through display of actual value and line fault type. All versions with removable connection terminals. In addition to screw connection technology, the devices are also available throughout with spring connection for fast, maintenance-free and vibration-proof connection. An automatic rotation direction correction is possible upon request. A version with IO-Link is available for the communication connection. In addition, devices with SIL 1/PL c certification are available.The comprehensive accessories, such as device identification labels, spare terminals and sealing covers, are uniform for all relays.The 3UG5 network monitoring relays replace the tried and tested 3UG4 series.SIRIUS relays - a program for all situations.
