SASUN AUTOMATIC CHANGEOVER big 250A 4POLE (THREE PHASE) SASUN
A SASUN Automatic Changeover Switch (ATS) 250A, 4-Pole, Three-Phase is an electrical device that automatically transfers the power supply between the main utility (grid) and a backup generator whenever there is a power outage or the mains supply returns.
Main uses
Automatically switches to generator power when the mains supply fails.
Returns to mains power when utility power is restored.
Ensures continuous power to critical equipment without manual intervention.
Protects electrical equipment from incorrect or unsafe power switching.
The 4-pole design switches all three phase conductors plus the neutral, providing complete isolation between the utility and generator supplies.
The 250A current rating makes it suitable for medium to large electrical loads.
Common applications
Commercial buildings
Factories and industrial plants
Hotels
Hospitals and healthcare facilities
Schools and universities
Office buildings
Large residential properties
Solar-generator hybrid systems
