{"product_id":"solar-ats-transfer-switch-100a","title":"Automatic Transfer Switch 100A 4-Pole 3-Phase ATS | Voltacon","description":"\u003cp\u003eA 100A 4-pole automatic transfer switch (ATS) built for dual-source AC power systems running at 400V AC. It switches automatically between a solar inverter output and a grid or generator supply, so only one source ever feeds the load. Automatic and manual operation are both supported, with a switching time under 2 seconds.\u003c\/p\u003e\u003ch2\u003eAutomatic transfer switch for solar inverter and grid backup\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRating\u003c\/strong\u003e, 100A rated current, 4-pole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e, Rated voltage AC 440V, working voltage AC 220V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e, 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitching time\u003c\/strong\u003e, under 2 seconds, using zero-crossing switching for emergency disconnection of both sources at once\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterlocking\u003c\/strong\u003e, mechanical and electrical interlock stops both sources from being connected together\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing\u003c\/strong\u003e, PC plastic enclosure, 244 x 118 x 145mm, rated for over 8,000 operating cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eOperating modes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMain power active\u003c\/li\u003e\n\u003cli\u003eStandby power active\u003c\/li\u003e\n\u003cli\u003eBoth sources isolated (I-0-II)\u003c\/li\u003e\n\u003cli\u003eEmergency manual operation\u003c\/li\u003e\n\u003cli\u003eElectronic remote control\u003c\/li\u003e\n\u003cli\u003eAutomatic switching with dynamic state monitoring\u003c\/li\u003e\n\u003cli\u003eEmergency disconnection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eUsed in solar off-grid systems to switch between inverter output and grid backup, in generator changeover for hybrid and off-grid installations, and in three-phase backup power systems for commercial and industrial dual-source AC distribution.\u003c\/p\u003e\u003ch3\u003eBuilt-in protection\u003c\/h3\u003e\u003cp\u003eA built-in DC switch provides short circuit, fire protection and double-break functions, alongside clear on\/off position indicators and padlock provisions.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x 100A 4-pole automatic transfer switch\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFitting must be carried out by a qualified electrician.
