Millisecond-level fast dual power automatic transfer switch (ATS) with a 15kA breaking capacity – high-safety power switch

The Dual Power Automatic Transfer Switch 63A is a high-performance millisecond-level fast switching ATS designed to ensure uninterrupted power supply when switching between two independent power sources. It automatically detects the status of the primary power source and seamlessly transfers the load to the backup source within milliseconds the moment the primary fails, drops below acceptable voltage, or becomes unstable. This near-instant switching means your critical loads — household appliances, solar inverter systems, communication equipment, refrigeration, lighting and essential circuits — continue operating without shutdown, restart or interruption.

With a rated current of 63A, this Dual Power Automatic Transfer Switch 63A is suitable for single-phase AC systems and fits standard DIN rail mounting, making installation clean, fast and compatible with standard distribution boxes. It supports both fully automatic operation and manual switching mode, giving installers and users flexibility during commissioning, testing and maintenance. In automatic mode, the unit continuously monitors the main power supply; upon detecting voltage loss or anomaly, it switches to the backup source — such as a generator, battery inverter, solar power system or alternate utility feed — quickly and reliably. When main power is restored, it automatically switches back after a short confirmation delay to avoid frequent or unnecessary transitions.

This Dual Power Automatic Transfer Switch 63A features clear status indicators and a simple, intuitive wiring layout, helping to reduce installation errors and simplify troubleshooting. Designed for safety and durability, it includes built-in protection mechanisms such as undervoltage detection, phase monitoring and anti-reverse switching logic. The compact body saves panel space while delivering reliable performance suitable for long-term continuous use in residential, commercial, small industrial and off-grid solar applications.

Typical applications for this Dual Power Automatic Transfer Switch 63A include:
– 🏠 Residential backup — switch between grid and home generator or battery system during blackouts
– ☀️ Solar & hybrid systems — combine utility power with solar inverter or battery backup
– 🏢 Commercial standby — protect offices, shops, servers and equipment from supply interruptions
– 📡 Communication & security — maintain power for routers, cameras, alarms and control systems
– 🏡 Off-grid & holiday homes — seamless switching between generator and renewable sources
– 🔧 Workshops & small industry — reliable power transfer for machinery and lighting circuits
