It operates on a 200-480 V AC supply, carries a Level 4 Touch controller, and withstands 42 kA for 0.1 s (Icw). The open-style unit uses a delayed I-O-II transition and top-fed line terminals.\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\u003eOXB500E3S4QT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1SCA151743R1001\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\u003eTruONE Automatic Transfer Switch\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 (Ie)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500 A (200-415 V AC)\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\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSwitched, simultaneous function, left and right side position\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\u003e12 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Short-time Withstand Current (Icw, 0.1 s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e42 kA rms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConventional Free-air Thermal Current (Ith at 40°C)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500 A\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 (open style, I-O-II operation)\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\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\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\u003ePower Loss\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e17.2 W per pole, 51.6 W total\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\u003e512 x 313 x 212 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\u003e21.63 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEAN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6417019822648\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 switched fourth pole on this 500 A unit breaks the neutral together with the three phases, which TN-S or TT systems with multiple earth points typically need to avoid circulating neutral currents during transfer. The Level 4 controller adds a touchscreen for on-device commissioning, event logging and diagnostics, useful on sites where a dedicated screen replaces laptop-based setup tools. Top-fed line terminals (QT) suit panels wired with incoming supply above the switch; pick the QB variant instead when busbars feed in from below.
