It watches for phase failure, wrong phase sequence, asymmetry, frequency drift, and over- or undervoltage conditions on a 3x 90-690 V AC supply running between 15 and 70 Hz. Two changeover contacts give you the switching outputs, and the screw terminals make for a solid, vibration-resistant connection out here in the plant. The wide voltage range — 90 to 690 V AC — means this relay can sit on anything from a 110 V control transformer up to a 690 V motor feeder without needing a separate PT. That 2-changeover contact arrangement gives you one set for alarm and one for trip, or you can wire them in series for a redundant safety path. RoHS compliant since June 2023. REACH Article 33 duty to inform applies due to lead content above 0.1% w/w (CAS 7439-92-1). No export restrictions — AL: N, ECCN: N. The packaging dimensions (125 x 110 x 33 mm) fit a standard DIN-rail footprint, and the unit ships as a single piece.","metaTitle":"Siemens 3UG5616-1CR20 Line Monitoring Relay, 3x90-690 VAC","metaDescription":"Siemens 3UG5616-1CR20 digitally adjustable monitoring relay for phase failure, sequence, asymmetry, frequency, over/under voltage. 3x90-690 VAC, 15-70 Hz, 2 changeover contacts.
