The 40–63A automatic transfer switch is an ideal solution for photovoltaic systems, generators, and residential or commercial installations that require uninterrupted power supply. It automatically detects the loss of the main supply and switches to the backup, ensuring seamless operation of the loads. Its 4-pole (4P) construction makes it suitable for three-phase circuits, but it can also be used in single-phase applications. It easily mounts on a DIN rail, providing a safe and neat installation inside the panel.

• Automatic transfer between main and backup supply
• Suitable for photovoltaic systems, generators, or UPS
