Its 21D controller handles the transfer logic on board, and the unit withstands 2.5 kA for 1 s (Icw) during a downstream fault, before the upstream protection device needs to clear it.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCatalog No\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOTM63F4C21D400C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1SCA151255R1001\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\u003eCompact ATS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEAN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6417019815688\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDegree of Protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFront IP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePollution Degree\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e286 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e103 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Depth\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e131 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.11 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eController Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e21D\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\u003e63 A at 40 degrees C\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\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\u003ePosition of Line Terminals\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSupplies on Top - Load on Bottom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMotor Operational Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e380...415 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBase mounting or DIN-rail mounting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Operational Voltage (Main Circuit)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e380...415 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Operational Current AC-23A (Ie)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e63 A (380-415 V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Operational Power AC-23A (Pe)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 kW (380-415 V)\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\u003e800 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 Short-time Withstand Current (Icw)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.5 kA for 1 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTerminal Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eScrew terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransition Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOpen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe 21D controller on this 63 A unit is self-supplied, so it needs no external control transformer or UPS to run the automatic transfer logic. Icw of 2.5 kA for 1 s sets how long the switch can carry a downstream fault before the upstream breaker must clear it - size the upstream protection trip time accordingly.
