Features of 250 Amp Automatic Transfer Switch

  • 【Double Row Compound Contact】Reliable mechanical interlock and electrical interlock are adopted, and an independent load isolation switch is adopted for actuating components to ensure safe and reliable operation.
  • 【Load Isolation Switch】Zero flashover (no arcing shield) is basically realized by using double row compound contact/horizontal pull mechanism/micro-motor pre-storage and micro-electronic control technology.
  • 【Saves Energy】The driver motor of the operator only passes the current at the moment when the load isolation switch is switched, which saves energy significantly.
  • 【High Precision Control】Carry out load isolation switch with mechanical interlock device to guarantee that common and standby power supply work reliably without interference
  • 【Emergency Manual Operation】Four operating functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, automatic control operation
