It accepts 90–690 V AC across 15–70 Hz, with or without a neutral conductor, and includes phase sequence correction — useful when incoming phase rotation is unpredictable or a motor rotation direction must be enforced without rewiring. The spring-cage design cuts installation time compared to screw clamps and holds reliably under vibration common in panel environments. RoHS compliance is confirmed effective June 1, 2023. ## Mounting and terminal notes The spring-loaded terminals accept 0.2–2.5 mm² conductors; strip length per typical Siemens spring-cage practice is 8–10 mm. No special tooling needed beyond a screwdriver to depress the cage.","metaTitle":"Siemens 3UG5618-2CR20 Line Monitoring Relay, 90-690 V AC, 15","metaDescription":"Active digitally adjustable monitoring relay for phase failure, sequence, asymmetry, frequency, over/undervoltage. 2 changeover contacts, spring terminals.
