the recommended 500 A gG \/ 400 A aM short-circuit backup must be sized before installation since this relay, like the GV2 L and GV3 L circuit-breaker combinations it is designed alongside, has no internal short-circuit withstand rating of its own. Differential (phase-unbalance) detection trips the relay on a single-phasing fault ahead of the class 10A thermal curve, and the 1NO+1NC trip contact wires directly into the EasyPact TVS contactor's control circuit for automatic disconnection.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50230323216667,"sku":"LRE487","price":296.33,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lre487-easy-tesys-overload-relay.jpg?v=1790901162","url":"https:\/\/stoklink.com\/products\/schneider-electric-lre487-easy-tesys-overload-relay","provider":"Stoklink","version":"1.0","type":"link"}
