Dry running protector  DR

Current detection type idle operation prevention device. It detects the decline (lower limit) of load current in idle operation and air suction operation, and stops the pump. Moreover, overload can also be detected.

  • Displays the set current value
  • Upper/lower limit can be set Upper limit: overload Lower limit: Idle operation, air suction operation, suction side cutoff operation
  • Built-in current transformer
  • Equipped with DIN rail
