The automatic transfer switch ATS 4P 63A

The ATS 4P 63A Automatic Transfer Switch is a professional-grade solution designed to automatically switch between two power sources – main supply and backup (generator, UPS, or alternative source). It ensures continuous power supply by instantly transferring the load when the primary source fails.

With an ultra-fast switching time of less than 50 milliseconds, this ATS guarantees minimal interruption, making it ideal for critical applications such as industrial systems, commercial buildings, server rooms, and backup power installations.

This model is a 4-pole (4P) switch rated at 63A, specifically designed for three-phase systems, providing full isolation of all lines including neutral. It supports both automatic and manual operation modes for maximum flexibility.
