4-pole 100A automatic transfer switch for seamless changeover between mains and generator or solar.
Description
The 4-Pole 100A ATS (Automatic Transfer Switch) provides seamless, hands-free switching between two power sources — typically mains electricity and a standby generator or solar inverter system. When the primary source fails, the ATS detects the outage and automatically transfers the load to the backup source within seconds, then switches back when mains power is restored. The 100A rating handles entire residential buildings, shops, and small commercial premises. The 4-pole design switches all three phases plus neutral, ensuring complete isolation and safe transfer. DIN-rail or panel-mountable for installation in main distribution boards.
