ATyS p M 4P - set (125 A, 230/400 V AC)
Article number: 70 745- ATyS p M are 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 a display with precise input of individual values. In addition, they are equipped with a switching contact for generator control and user programmable inputs and outputs.
- ATyS p M - the set consists of the basic ATyS p M device, terminal shrouds, auxiliary contacts and bridging bar. The set therefore contains all necessary accessories for the selected model.
