Phase-unbalance detection trips the relay on a single-phasing fault even before the thermal element reaches its class 10A curve, which the plain (non-differential) LRD\/LR9D equivalents do not provide. The relay clips directly onto the LC1K contactor's bottom terminals to form a compact starter, so no separate mounting plate is needed unless the LA7K0064 terminal block is fitted for remote placement away from the contactor.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50230506914075,"sku":"LR2K0303","price":36.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lr2k0303-tesys-lrk-overload-relay.jpg?v=1790901139","url":"https:\/\/stoklink.com\/products\/schneider-electric-lr2k0303-tesys-lrk-overload-relay","provider":"Stoklink","version":"1.0","type":"link"}
