  NA718  Motor Protector Specifications  

  

♦Main Functions

F Current display: display three average current, press key to display A,B,C phase current respectively.

F Overload protecting: when three phase average current exceed rated current, circuit protects and load opens.

F Deficient-phase protecting: when testing deficient-phase or three phase current unbalance, circuit protects and load opens.

F Auto reset: when circuit protects and load opens, can set “reset automatically” degree and time, after some time, switch on load again, if circuit still has malfunction, try several times, then must reset manually.
