It watches three-phase mains for phase failure, phase sequence, asymmetry, frequency deviation, and over- or under-voltage conditions across a 90–690 V AC range at 15–70 Hz. Two changeover contacts signal the fault; spring-loaded terminals speed wiring in the panel. ## Key ratings in practice The wide voltage window (90–690 V AC) covers low-voltage distribution up to 690 V line-to-line, so it handles standard 400 V and 480 V systems without a separate PT. The 15–70 Hz frequency range means it works on 50 Hz and 60 Hz networks plus variable-frequency gensets. Two changeover contacts give independent NO/NC pairs for separate alarm and trip paths — one to a PLC input, one to a contactor coil.","metaTitle":"Siemens 3UG5616-2CR20 Line Monitoring Relay, 90-690 VAC, 15-","metaDescription":"Active Siemens 3UG5616-2CR20 digitally adjustable monitoring relay for phase failure, sequence, asymmetry, over/undervoltage. 2 changeover contacts, spring terminals.
