Automatic transfer switching equipment from 125 to 3200A

ATyS t and ATyS G are 3 or 4 pole automatic transfer switches, with positive break indication. They incorporate all the functions offered by the ATyS d, as well as function intened for mains/mains applications (ATyS t) and mains/genset applications (ATyS g).
In automatic moad they enable the monitoring of, and the onload changeover between, two power supply source, in accordance with the parameters configured via two potentionmeters and four DIP switches.

Rapid commissioning
ATyS t and g switches offer significant time saving during commissioning (process takes 2 to 3 minutes). Owing to the design that allows commissioning through just two potentiometers (4 on the ATyS g) and four DIP switches, a scrrewdriver is all that is required to configure the parameters. For added simplicity, they also offer an autoconfiguration function which enables automatic adjustment of the rated voltage and frequency.

ATyS t : specifically designed for mains/mains application
The ATyS t’s integrated controller has been designed to provide only the functions required for these application (operation with or without priority, preferred source selection) together with the monitoring of the voltage and frequency of both source, for three-phase and single-phase networks.

ATyS g : specifically designed for mains/genset applications
The ATyS g’s integrated controller has been designed to provide specific functions for these applications (genset startup, on-load or off-load tests…) together with the monitoring of the voltage and frequency of both sources for three-phase and single-phase networks.The generator supply must be connected to switch II, located at the rear.
