Lovato ATL600/610 Automatic Transfer Switch


Lovato ATL600/610 Automatic Transfer Switch for 2 Supply Lines.

The automatic transfer switch controllers ATL 600 (non-expandable) / ATL 610 (expandable with EXP… expansion modules)  are used for the automatic or manual switching of the load from the MAIN LINE to a stand-by or emergency SECONDARY LINE and vice-versa. They have two outputs for the “automatic” and/or “manual” control of contactors or motorised circuit breakers and switches.

The Lovato ATL600/610 is available with a range of expansion modules and accessories; click here to view all available Lovato expansion modules and accessories.
