Use the selection guide above to match your motor's HP and relay range to the correct reference number — an undersized relay setting is a common cause of nuisance tripping.
Description▾
During healthy mains supply, the load is drawn from mains only. When main supply fails and the standby Genset is ON, it automatically connects the load to the Generator. When main supply resumes, the connected load is automatically shifted back to mains.
AUTO TRANSFER SWITCH (ATS) performs the function of automatically switching the connected load among Mains or Genset (or any two power sources) in a specified manner with mains as first priority.
