where the average temperature to cover

Clicks:Updated:2013-10-19

 motor thermal protection test in two ways:
        1 analog test : the need for a stable and constant current power protection, then the protector to the power supply , then the current should be overload current protection device connected to the circuit after a predetermined period of time in the trip .
        2 matching test : Before turning on the main circuit , you need to protect the device connected to the motor , and then lock the motor rotor, power is turned on , if the thermal protection parameter value is set correctly , it will disconnect the power within a predetermined time , first trip time may be slightly longer , after a cycle or two after work , follow-up and 20 to see a break time should be close to the same tolerances. If at 20-30 seconds , still can not break the circuit protector , protector prove incorrect parameters , and you should immediately disconnect the main power supply to prevent motor burnout.

      Want more than the pure temperature sensor thermal protection, current protective device in contact with the surface there are no special installation requirements .
      We now have two current thermal protection can be selected : TS series and 3MPE series.
