The 3KC ATC6300 and ATC 6500 transfer control devices enables safe and fault-free switching between two power sources. The 3KC is deployed above all where a mains failure can have critical consequences. In case of power supply faults, it switches from a main power supply to a standby power supply. In doing so, it safeguards an uninterruptible power supply.


Safely disconnecting electrical systems from the power grid is essential to protecting humans as well as the systems themselves. The comprehensive portfolio of SENTRON switching devices for safe, standard-compliant, and efficient switching of electrical equipment protect humans from accidents and electrical systems from damage. You benefit from a flexible and more productive engineering process.
