EKF ATS device is designed to provide backup power supply to a load connected to a power supply system that has a main and a backup input. The ATS device automatically connects the backup power line in case of voltage loss on the main line. Designed for three-phase four-wire (or single-phase single-wire) dual AC power supply systems with a frequency of 50/60 Hz, rated voltage 400 V/230 V and rated current up to 63A. The device is made in the form of a monoblock and consists of a control unit and two modular circuit breakers. The control unit has a manual override lever. This design allows for reduced dimensions and installation area of the ATS.
