ATyS g M 4P - set (125 A, 230/400 V AC)

Article number: 70 715
  • ATyS g M are 2 pole and 4 pole modular automatic transfer switches with an integrated controller.
  • Their primary function is to switch between the main and backup supply in case of power failure. They work in automatic mode, if necessary the devices can be switched manually.
  • They are designed for low voltage power supply systems with a maximum current of 40 to 160 A for applications where a brief interruption of the load supply is acceptable during transfer.
  • They allow the setting of overvoltage, undervoltage and frequency thresholds.
  • They are set using potentioneters and microswitches on the front of the product. In addition, they are equipped with a switching contact for generator control.
  • ATyS g M - the set consists of the basic ATyS g M device, terminal shrouds, auxiliary contacts and bridging bar. The set therefore contains all necessary accessories for the selected model.
