{"product_id":"120401087","title":"Mains monitoring for phase sequence, failure, over-\/undervoltage, 380-480VAC – RM22TR33","description":"\u003cp\u003eHARMONY Control. This grid monitoring relay monitors three-phase networks (380-480 VAC) for phase sequence, phase failure, undervoltage and overvoltage. Two changeover contacts are available for signalling, which can be loaded up to 8 A. A limit value (-20--2%\/+2-+20%) can be set for undervoltage and overvoltage respectively, and a response or drop-out delay can be set for the output. Settings are made via controls on the front, which can be protected against changes by a transparent cover. A illuminated scale pointer makes it very easy to see the potentiometer setting even from a distance. The diagnostic switch on the front allows the output relays to be switched off to test the entire application. Closing the transparent cover automatically resets the diagnostic switch. Three LEDs indicate the status. The width is 22.5 mm and mounting is on a DIN rail. The cable connection is made via screw terminals.\u003c\/p\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":56140662636875,"sku":"120401087","price":135.31,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/5075\/6427\/files\/MD01_120401087.jpg?v=1766074846","url":"https:\/\/solarvic.at\/en\/products\/120401087","provider":"SOLARVIC | Photovoltaik \u0026 Haustechnik","version":"1.0","type":"link"}
