Used in solar PV systems to switch automatically between a solar inverter output and grid or generator supply, ensuring only one source feeds the load at any time. Supports both automatic and manual operation modes, with switching time under 2 seconds.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e100A rated current, 4-pole\u003c\/li\u003e\n  \u003cli\u003eRated voltage: AC 440V \/ Working voltage: AC 220V\u003c\/li\u003e\n  \u003cli\u003eFrequency: 50\/60Hz\u003c\/li\u003e\n  \u003cli\u003eSwitching time: under 2 seconds\u003c\/li\u003e\n  \u003cli\u003eBoth automatic and manual operation supported\u003c\/li\u003e\n  \u003cli\u003eZero-crossing switching technology for emergency disconnection of both sources simultaneously\u003c\/li\u003e\n  \u003cli\u003eMechanical and electrical interlocking: prevents both sources connecting simultaneously\u003c\/li\u003e\n  \u003cli\u003eBuilt-in DC switch: short circuit, fire protection and double-break functions\u003c\/li\u003e\n  \u003cli\u003eClear on\/off position indicators and padlock provisions\u003c\/li\u003e\n  \u003cli\u003eRated for over 8,000 operating cycles\u003c\/li\u003e\n  \u003cli\u003ePC plastic housing: 244 x 118 x 145mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe ATS monitors both connected power sources continuously. When the primary source fails or falls outside acceptable parameters, the switch transfers the load to the backup source automatically. When the primary source recovers, the switch returns the load and disconnects the backup. The mechanical interlock ensures the two sources can never be connected together, which protects both the inverter and the grid connection.\u003c\/p\u003e\n\n\u003cp\u003eThe zero-crossing switching function allows both sources to be disconnected simultaneously in an emergency, which is a requirement for fire protection systems in commercial installations.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eOperating Modes\u003c\/h3\u003e\n\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\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSolar off-grid systems switching between inverter output and grid backup\u003c\/li\u003e\n  \u003cli\u003eGenerator changeover for hybrid and off-grid installations\u003c\/li\u003e\n  \u003cli\u003eThree-phase backup power systems\u003c\/li\u003e\n  \u003cli\u003eCommercial and industrial dual-source AC distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 100A 4-pole automatic transfer switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation must be carried out by a qualified electrician.
