Its 36 kA breaking capacity at 415 V covers high fault-current environments typical of transformer secondaries up to ~630 kVA at standard impedance. The adjustable thermal-magnetic trip unit lets engineers dial in overload protection from 175 A to 250 A without changing the frame, reducing panel redesign time when load profiles shift. Three-pole construction handles three-phase distribution without a neutral pole, appropriate where neutral is bonded at the transformer.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":52404988215579,"sku":"3VA1225-4EF32-0AA0","price":356.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/3va1225-4ef32-0aa0_34e66cde-ff14-46ba-a761-ecbaf9d1a412.webp?v=1782491119","url":"https:\/\/stoklink.com\/products\/siemens-3va1225-4ef32-0aa0-sentron-3va12-250a-36ka-mccb","provider":"Stoklink","version":"1.0","type":"link"}
