Motor Protection

  • Serves as an electronic proof-of-operation; detects current draw changes in motors when they encounter problems such as pumps running dry or pending bearing failure
  • Non-intrusive, less expensive to install than differential pressure flow sensors or thermal switches. Much quicker response time than Class 10 overload relays
  • High Inrush or Temporary Overload Current

  • Adjustable start-up/delay timer allows 0-15 second delay to eliminate nuisance trips from high inrush or short overload conditions
