Siemens 3UG56182CR20 3UG5618-2CR20 digital voltage monitoring relay, phase failure content_copy

Digitally adjustable monitoring relay Phase failure, phase sequence, asymmetry, frequency, overvoltage and undervoltage monitoring, with/without N conductor with phase sequence correction 3x 90-690 V AC, 15-70 Hz 2 changeover contacts Spring-loaded connection Digitally adjustable network monitoring relay SIRIUS 3UG5 for monitoring phase sequence, failure and asymmetry, undervoltage and overvoltage as well as frequency, e.g. in unstable networks or mobile systems such as air conditioning compressors, refrigerated containers, construction site compressors, cranes or solar and wind power plants. Worldwide use thanks to wide voltage supply and international certificates. 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 a quick, maintenance-free and vibration-proof connection. Automatic correction of the direction of rotation is possible on request. A variant with IO-Link is available for the communication connection. In addition, devices with SIL 1/PL c certification are available. The comprehensive range of accessories, such as device identification plates, replacement terminals and sealing covers, is standard for all relays. The 3UG5 network monitoring relays replace the proven 3UG4 series. SIRIUS relays - a program for all cases.
