Transfer enclosed switches

ATyS Bypass 40 to 3200 A

  • Automatically switches between 2 sources to ensure continuity of the supply to critical loads such as sprinklers, lifts, water pumps, etc.
  • Assures continuity of service during service work, maintenance and testing.
  • Full isolation of the automatic switch for safe maintenance work.
  • By connecting an ATyS to a remote D20 interface, you can configure, operate and view the measurements at the front of the equipment (timer settings, thresholds and hysteresis, start/stop of the genset, etc.)
