A Level 4 touchscreen controller handles the delayed I-O-II transition, and the bottom-supply \/ top-load terminal layout suits switchboards where incoming feeders enter from below.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCatalog Designation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOXB250E3S4QB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1SCA152794R1001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAutomatic Transfer Switches TruONE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEAN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6417019840154\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Operational Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e200-480 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Operational Current AC-31B\/32B\/33B (Ie)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250 A (200-415 V AC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConventional Free-air Thermal Current (Ith)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250 A at 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Short-time Withstand Current (Icw)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18 kA for 0.3 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Insulation Voltage (Ui)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1000 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Impulse Withstand Voltage (Uimp)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Frequency\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50-60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eController Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLevel 4 (Touch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransition Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDelayed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecial Function\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOpen style\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHandle Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDirect Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTerminal Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBolt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePosition of Line Terminals\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSupplies on Bottom - Load on Top\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFourth Pole Position\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLeft and Right Side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFourth Pole Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSwitched - Simultaneous Function\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDegree of Protection \/ Pollution Degree\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP20 (Front), Pollution Degree 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Loss\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9.7 W per pole, 29.1 W total\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15.77 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (W x H x D)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e375 x 305 x 183 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eIEC 60947-6-1\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe 4P configuration switches the neutral along with the three phases, which matters on TN-S or TT installations where the two sources must not share a bonded neutral during transfer. Icw of 18 kA for 0.3 s at the 250 A frame sets the short-time withstand this unit can carry while upstream protection clears a fault, a factor in selective coordination studies. The Level 4 touch controller adds a graphical HMI with event history and parameter access beyond what the DIP or LCD controllers in the same frame offer, useful where operators need on-site diagnostics without a laptop. QB terminals bring supply in from the bottom and send load out the top; pick the QT variant instead if the switchboard busbars run the opposite way.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":50229247574299,"sku":"1SCA152794R1001","price":4053.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/abb-1sca152794r1001-oxb250e3s4qb-automatic-transfer-switch.png?v=1790957537","url":"https:\/\/stoklink.com\/products\/abb-1sca152794r1001-oxb250e3s4qb","provider":"Stoklink","version":"1.0","type":"link"}
