Conformity to standards

UL 1008 CSA-C22.2 No.178.1-14 Guide WPWR File E506172


Robust, reliable and high performing

Rated for emergency systems and total system without derating, these switches also include high short-circuit rating with specific breakers or fuses up to 100 kA.

Safe manual handle

The ATyS FT ensures the safety of your maintenance personnel thanks to patented safety features. Access to the manual handle is prohibited by a transparent polycarbonate cover requiring deliberate action to open. Once the cover is opened, the switch and the controller are electrically inhibited, preventing any unexpected transfer during maintenance. When using the main manual handle, the power switching characteristics are as reliable as when operated automatically, ensuring safe transfers in all cases.

Inspectable contacts

The ATyS FT is specifically designed to reduce the time it takes to inspect power contacts when utilizing the specific maintenance mode.
