(SVRR) is a three-phase monitoring relay designed specifically for grid feeding applications, ensuring safe and compliant connection of decentralized energy sources to the public grid. This relay monitors key grid parameters such as voltage, frequency, and phase failure in accordance with DIN V VDE V --: February . It is powered directly by the measuring circuit and provides two changeover (SPDT) contacts for control and signaling.\u003c\/div\u003e\u003cdiv\u003eThe device operates on a rated control and measuring voltage of  x  V AC (L-L) \/  V AC (L-N) and is suitable for both three-phase and single-phase mains monitoring. It features adjustable threshold values for the -minute average voltage (–% of Us), fixed thresholds for overvoltage, undervoltage, overfrequency, and underfrequency, and configurable neutral conductor connection. The relay includes start-up and restart delays ( s fixed), true RMS measurement, and front-accessible configuration and status LEDs for easy setup and diagnostics.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eKey Features:\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eGrid feeding monitoring for decentralized energy sources\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eRated voltage:  x  V AC (L-L) \/  V AC (L-N)\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e SPDT (changeover) contacts for control and signaling\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eTrue RMS measuring principle for accurate detection\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eMonitors: Overvoltage, undervoltage, overfrequency, underfrequency, phase failure\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eAdjustable -minute average voltage threshold (–% Us)\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eStart-up and restart delay:  s fixed\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eConfigurable neutral conductor connection\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eFront-panel LEDs for relay status and fault indication\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eDIN rail mounting (. mm width)\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eDegree of protection: IP (enclosure), IP (terminals)\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eCompliant with DIN V VDE V --:\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003e•\u003cspan class=\"Apple-tab-span\" style=\"white-space:pre\"\u003e\t\u003c\/span\u003eCompact dimensions: . ×  ×  mm\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":55878905987446,"sku":"EB-286690552345","price":94.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/4202\/8857\/files\/57_b82f32b0-0161-4cdb-b757-20c533474366.png?v=1751749922","url":"https:\/\/volt-werk.com\/products\/abb-cm-ufs-1-1svr630736r0300-three-phase-grid-feeding-monitoring-relay","provider":"VOLTWERK Handel","version":"1.0","type":"link"}
