Description
Pramac LTS 250A Automatic Transfer Switch
The Pramac LTS 250A Automatic Transfer Switch (ATS) automatically takes over when mains power fails, quickly detecting the outage, starting your backup generator (via ACP connection), and switching your load over smoothly — usually in seconds — to keep everything running without missing a beat.
When the grid comes back online and is stable, it safely returns power to mains and shuts down the generator. This motorized 4-pole model is designed specifically for 400V three-phase systems and provides reliable, high-capacity performance for medium to large commercial premises, industrial facilities, workshops, farms, offices, or heavy-duty backup applications. The panel-mounted design with high-quality motorized changeover switch ensures easy integration, and it’s engineered to work seamlessly with Pramac generators equipped with ACP/AMF controls.
Set it up once and forget it — dependable automatic backup switching when you need it most.
