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


Benefits

Prevents downtime during power outages.

Eliminates the need for manual changeover.

Improves electrical safety by preventing back-feeding between power sources.

Provides reliable, uninterrupted power to essential loads.

Saves time and reduces the risk of human error.


A 250A, 4-pole, three-phase SASUN ATS is typically installed where a large three-phase electrical system requires automatic, safe, and uninterrupted switching between the utility supply and a standby generator.
