Frequency monitoring is fixed to 15–70 Hz, so it works on 50 Hz and 60 Hz systems but also on variable-frequency gensets or low-frequency shipboard supplies. The Bluetooth interface is not a control bus — it is a commissioning and diagnostic tool; the relay still trips hardwired contacts. Spring-loaded terminals accept 0.2–2.5 mm² with ferrule; strip length 8 mm. The 38 mm housing width fits one standard DIN-rail module. The 3UG5716-2CR20 is an active, current-production item. RoHS compliance effective 01 June 2023; Export classification is AL: N / ECCN: EAR99 — no special license required for most destinations. Group Code R711 and Product Group 5885 are internal Siemens cataloging fields; they do not affect fit or function.","metaTitle":"Siemens 3UG5716-2CR20 Digital Monitoring Relay, Phase/Voltag","metaDescription":"Active Siemens 3UG5716-2CR20 digital monitoring relay: phase failure, sequence, asymmetry, over/undervoltage, frequency (15-70 Hz), 90-690 V AC, Bluetooth, 2 CO contacts, spring te","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Process / Temperature Controllers"],"specifications":{"title":"3UG5716-2CR20","Group Code":"R711","description":"digital monitoring relay phase failure, phase sequence, asymmetry, frequency, overvoltage and undervoltage monitoring with Bluetooth 3x 90-690 V AC, 15-70 Hz 2 changeover contacts spring-loaded terminal","Product Group":"5885","Product class":"A: Standard product which is a stock item could be returned within the returns guidelines/period.","Quantity Unit":"1 Piece","Product Family":"Line monitoring","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : EAR99","Packaging dimensions (L x W x H)":"127.00 x 111.00 x 38.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-06-23","REACH Art. 33 Duty to inform according to the current list of candidates":"Lead CAS-No. 7439-92-1 > 0,1 % (w / w)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/93a404ed942e4c4a41acbc03f1850c54.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3UG5716-2CR20?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation is available for the 3UG5716-2CR20?","answer":"RoHS compliance effective 01 June 2023.
