Its TM-D thermal-magnetic trip unit gives fixed long-time overload protection (L) and instantaneous short-circuit protection (I) fixed at 10 x In (1250 A), fixed-mounted to a backplate for distribution-board incomers and

cannot drift after commissioning — the trade-off against the adjustable (A) variant at the same current, which allows the thermal pick-up to be tuned down to 125 A. Choose this fixed version when the circuit's load current is known and stable and a tamper-proof setting is preferred over field adjustability. Rated service breaking capacity (Ics) is 50% of Icu (15 kA of 30 kA) at 380\/415 V AC, in line with the 125 A frame's Category A duty. The fourth pole trips the neutral at the same Ir setting as the phases (4P\/4D), so the breaker protects a 3-phase-plus-neutral feeder without a separate neutral device.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229468496155,"sku":"G12F4F125","price":108.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-g12f4f125-gopact-mccb-125.jpg?v=1790868153","url":"https:\/\/stoklink.com\/products\/schneider-electric-g12f4f125-gopact-mccb-125","provider":"Stoklink","version":"1.0","type":"link"}
