Used with a VigiPacT RM12T multiplexer for up to 12 measurement channels, it issues a control signal when the per-channel residual current, adjustable from 30 mA to 30 A, exceeds the set threshold.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLV481004\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\u003eRange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVigiPacT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDevice\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVigirex RMH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMonitoring relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFront panel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType of setting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKeypad, Modbus address\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEarth-leakage sensitivity (per channel)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.03-1 A (step 0.001 A); 1-30 A (step 0.1 A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEarth-leakage time delay\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eInstantaneous at 0.03 A; adjustable 0-4.5 s for 0.03-30 A (step 10 ms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent sensors \/ multiplexer compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVigiPacT TOA, A and L sensors; VigiPacT RM12T multiplexer (up to 12 channels)\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\u003e220-240 V AC 50\/60 Hz (70-110%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Ithe] Conventional enclosed thermal current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMonitored distribution system\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 1000 V AC at 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEarthing system\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTN-S, IT, TT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Uimp] Rated impulse withstand voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTest function\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLocal, remote test via communication\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommunication service\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eModbus slave\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal contacts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 C\/O alarm (fail-safe); 1 NO pre-alarm (fail-safe)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (W x H x D)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e72 x 72 x 117 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.3 kg\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\u003eIP40 front face\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient temperature (operation)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-25...55 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEN\/IEC 60947-2 Annex M\u003c\/li\u003e\n\u003cli\u003eEN\/IEC 60755\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe RMH is a monitoring relay, not a protection relay: it issues an alarm signal but does not itself trip the associated circuit breaker, so pick the RHU or RHUs instead where automatic tripping on a residual-current fault is required. Pairing it with the RM12T multiplexer lets one RMH watch up to 12 separate feeders for early insulation degradation, which suits preventive-maintenance monitoring across a distribution board rather than single-circuit protection. Automatic reset after a fault clears keeps the monitoring loop running without a manual step at the panel.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229502116123,"sku":"LV481004","price":718.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lv481004-vigirex-rmh-monitoring-relay.jpg?v=1790869436","url":"https:\/\/stoklink.com\/products\/schneider-electric-lv481004-vigirex-rmh","provider":"Stoklink","version":"1.0","type":"link"}
