It is a type B relay, so it detects smooth DC residual currents in addition to AC and pulsating DC, and trips the associated circuit breaker via a compatible type B toroid when the set threshold is exceeded.\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\u003eLV481010\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 RHB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eResidual current protection relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEarth-leakage protection class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eType B\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEarth-leakage sensitivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.03-0.1 A (step 0.001 A);

the front-panel-mount RHUs\/RHU cover type A applications instead. Its type B class is the deciding factor versus the type A relays: pick the RHB where downstream equipment (variable speed drives, UPS, EV chargers) can generate smooth DC earth-fault currents that a type A relay cannot detect. Continuous self-monitoring of the electronics, power supply and sensor link, combined with remote reset, suits unattended installations where a latent relay fault needs to be flagged rather than discovered at the next real fault.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229502181659,"sku":"LV481010","price":1121.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lv481010-vigirex-rhb-residual-current-relay.jpg?v=1790869446","url":"https:\/\/stoklink.com\/products\/schneider-electric-lv481010-vigirex-rhb","provider":"Stoklink","version":"1.0","type":"link"}
