Siemens 3UG4615-1CR20 Three Phase & Mains Voltage Monitoring Relay Digital N/A
Digital monitoring relay for 3-phase mains voltage switchable phase sequence phase failure 3 x 160 to 690 V AC 50 to 60Hz under and over voltage. 160-690V Hysteresis 1-20 V each 0-20 s for Umin and Umax 1 W for Umin 1 W for Umax screw connection Successor product for 3UG3041-1BP50 digitally adjustable SIRIUS 3UG4 line monitoring relay for monitoring phase sequence, 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 application through wide-voltage supply and international certificates. The relay can be set variably to over-, under-shoot 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 by displaying actual value and line fault type. All versions with removable connection terminals.In addition to screw connection technology, the devices are also continuously available with spring-type terminals for a fast, maintenance-free and vibration-proof connection. They are also available in various voltages, either with IO-Link or with automatic direction correction.The comprehensive accessories, such as device identification plates, insertion lugs and cover caps, are uniform for all relays.SIRIUS relay - a program for all cases.This text is machine translated.
