Automatic Transfer Switch | 400A

The 400A Load Transfer Switch Panel offers a fully-automatic solution for switching between mains power and generator backup in commercial and industrial settings.

Automatic, rapid transfer from mains to generator ensures uninterrupted power.

This automatic transfer switch (ATS) is engineered for seamless mains-to-generator changeover in the event of a power outage. With reliable 400A capacity and motorised four-pole switching (switched neutral), it is designed for high-capacity three-phase systems, ideal for commercial, industrial, and backup power applications.
