It reports phase rotation order and loss via two changeover contacts terminated on spring-loaded terminals — no screwdriver needed for wiring, which shaves time off panel assembly and re-termination. The 160–690 V AC range covers standard low-voltage motor supplies (400 V, 480 V, 690 V) without needing a separate voltage variant. Two changeover contacts give independent signalling to a PLC and a local alarm lamp from the same relay. No torquing, no screw check during commissioning — just strip to 8–10 mm and push in. For a panel with a dozen monitoring relays, that adds up to real labour savings. RoHS compliant since 01 June 2023. No export control restrictions (AL: N / ECCN: N). Part of the Siemens Line Monitoring family. The 126 x 111 x 36 mm envelope leaves finger room for adjacent terminals. Two changeover contacts rated for typical control voltages (24 V DC, 230 V AC) — check the contact rating against your load before wiring.","metaTitle":"Siemens 3UG5511-2BR20 Monitoring Relay, Phase Sequence, 160-","metaDescription":"Active production.
