The magnetic short-circuit trip is fixed at 12 x In (3000 A) rather than independently adjustable, so coordination with downstream devices depends on time-current curve separation rather than an Isd setting. At 25 kA Icu at 380\/415 V AC, the B performance level covers general distribution duty on this 250 A frame; where a higher prospective fault current is expected, the equivalent N or H breaking-capacity variant in the same frame is the better fit.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54076230467867,"sku":"G25B4A250","price":274.74,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-g25b4a250-gopact-mccb250b-mccb.jpg?v=1790868016","url":"https:\/\/stoklink.com\/products\/schneider-electric-g25b4a250-gopact-mccb250b-250a","provider":"Stoklink","version":"1.0","type":"link"}
