Where the monitored circuit is a single-phase 1-100 V or 15-500 V signal rather than a 3-phase line voltage, the RM22UA32MR or RM22UA33MR single-phase voltage relays in the same 22.5 mm housing are the correct siblings instead. Reliability data rates RM22TR33 at B10d = 350,000 operations and an MTTFd of 388.1 years, figures worth pulling into a mission-time calculation if the relay feeds a safety-related shutdown circuit downstream rather than just an alarm indicator. The front test button triggers each monitored condition in turn for commissioning checks without having to force an actual supply fault, cutting first-start troubleshooting time on new panel builds.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54074862305563,"sku":"RM22TR33","price":63.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-rm22tr33-harmony-control-relay.png?v=1790851517","url":"https:\/\/stoklink.com\/products\/schneider-electric-rm22tr33-control-relay","provider":"Stoklink","version":"1.0","type":"link"}
