It switches two separate 5 A changeover contacts with an adjustable 0.1-10 second fault delay, in a 35 mm wide DIN rail housing.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRM35HZ21FM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGTIN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3389119405201\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRange of Product\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHarmony Control Relays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRelay Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRM35HZ21FM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRelay Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFrequency control relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRelay Monitored Parameters\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOverfrequency and underfrequency, 50 or 60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Us] Rated Supply Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e120-277 V AC, non self-powered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e40-70 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThreshold Setting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-2 to 10 Hz \/ -10 to 2 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTime Delay Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAdjustable 0.1-10 s, +\/- 10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput Contacts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 C\/O + 1 C\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNominal Output Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSwitching Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1250 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReset Time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2000 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIP Degree of Protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP20 terminals, IP30 casing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting Support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e35 mm symmetrical DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWidth\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.4 in (35 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCE\u003c\/li\u003e\n\u003cli\u003eGL\u003c\/li\u003e\n\u003cli\u003eUL\u003c\/li\u003e\n\u003cli\u003eCSA\u003c\/li\u003e\n\u003cli\u003eIEC 60255-6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe two independent 1 C\/O outputs on RM35HZ21FM let an over-frequency trip and an under-frequency trip drive separate downstream circuits - useful for generator or wind-turbine protection where over-speed and under-speed events need different responses rather than a single shared alarm contact. Its 120-277 V AC supply range covers both 120 V and 230\/277 V control circuits without a separate SKU, and the -2 to 10 Hz and -10 to 2 Hz threshold settings let each output be tuned independently around the 50\/60 Hz nominal. Rated for up to 360 operations per hour under full load and immune to supply microbreaks as short as 10 ms, RM35HZ21FM tolerates momentary disturbances without a nuisance trip, a relevant spec where the monitored source is a diesel genset or inverter with a noisier frequency output than utility mains.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54074862240027,"sku":"RM35HZ21FM","price":99.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-rm35hz21fm-harmony-control-relay.png?v=1790851517","url":"https:\/\/stoklink.com\/products\/schneider-electric-rm35hz21fm-control-relay","provider":"Stoklink","version":"1.0","type":"link"}
