Driven by a 220-240 V AC motor operator, it carries a 50 kA short-time withstand current (Icw, 1 s) and an open-transition sequence.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e1SCA112702R1001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMotorized Change-over Switches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog Designation\u003c\/td\u003e\n\u003ctd\u003eOTM1250E4CM230C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEAN\u003c\/td\u003e\n\u003ctd\u003e6417019453941\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Poles\u003c\/td\u003e\n\u003ctd\u003e4P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFourth Pole Type\u003c\/td\u003e\n\u003ctd\u003eSwitched - Simultaneous Function\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFourth Pole Position\u003c\/td\u003e\n\u003ctd\u003eRight Side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransition Type\u003c\/td\u003e\n\u003ctd\u003eOpen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Operational Voltage (Main Circuit)\u003c\/td\u003e\n\u003ctd\u003e1000 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Operational Current AC-21A\/AC-22A\/AC-23A (Ie)\u003c\/td\u003e\n\u003ctd\u003e1250 A (at 380-415 V, 500 V, 690 V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Operational Power AC-23A (Pe)\u003c\/td\u003e\n\u003ctd\u003e710 kW at 380-415 V, 900 kW at 500 V, 1200 kW at 690 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Operational Current AC-31B \/ AC-33B (Ie)\u003c\/td\u003e\n\u003ctd\u003e1250 A \/ 1000 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Short-time Withstand Current (Icw)\u003c\/td\u003e\n\u003ctd\u003e50 kA for 1 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Insulation Voltage (Ui)\u003c\/td\u003e\n\u003ctd\u003e1000 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Impulse Withstand Voltage (Uimp)\u003c\/td\u003e\n\u003ctd\u003e12 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConventional Free-air Thermal Current (Ith)\u003c\/td\u003e\n\u003ctd\u003e1250 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Operational Voltage\u003c\/td\u003e\n\u003ctd\u003e220-240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDegree of Protection\u003c\/td\u003e\n\u003ctd\u003eIP20 (front)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eBase mounting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Dimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e587 x 306 x 297 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e65 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe switched, simultaneous fourth pole on the right side makes this the version to specify when the neutral must transfer along with the three phases, unlike a 3-pole switch that leaves neutral solidly connected. The extra pole adds 80 mm of width and 10 kg of weight over the equivalent 3-pole 1250 A enclosure, so confirm panel clearance before substituting it in. Current, voltage and short-time withstand ratings otherwise match the 3-pole 1250 A switch in this range exactly.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":50229280735515,"sku":"1SCA112702R1001","price":5184.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/abb-1sca112702r1001-otm1250e4cm230c-transfer-switch.jpg?v=1790957050","url":"https:\/\/stoklink.com\/products\/abb-1sca112702r1001-otm1250e4cm230c","provider":"Stoklink","version":"1.0","type":"link"}
