Suntree Automatic Changeover\/Transfer Switch (ATS) Rail Mounted 63A Key Features & Functionality<\/div>\n

<\/h2>\n
    \n
  • Dual Power Management:<\/strong> Automatically switches to the secondary\/backup power supply when the primary line experiences a power failure or voltage drop, and returns automatically when grid power stabilizes.<\/span>\u00a0<\/li>\n
  • Safety & Protection:<\/strong> Equipped with open-phase, loss-of-voltage, and built-in overload\/short-circuit protection (on CB-class models) to preserve downstream appliances.<\/span>\u00a0<\/li>\n
  • Visual Status Indicators:<\/strong> Built-in LED indication lamps provide real-time updates on which power source is currently active.<\/span><\/li>\n
  • Installation Design:<\/strong> Designed to fit standard 35mm Din-Rails inside distribution boards, lowering overall installation footprint and complexity<\/span><\/li>\n<\/ul>\n
