1. device, this device comprises:

  • Current inductor, this current inductor are arranged to the electric current and the signal that is used to produce corresponding to the electric current of sensing in the sensor circuit protection equipment;

    Reception is corresponding to the controller of the signal of the electric current of sensing, and this controller is arranged on the basis of the thermal characteristics of electric circuit protection equipment and the electric current sensed, and the heat load of the accumulation of electric circuit protection equipment is estimated;

    AndBe arranged to the xegregating unit that optionally separates electric circuit protection equipment,If wherein Lei Ji heat load surpasses the predetermined maximum heat load of electric circuit protection equipment, controller is further configured to provide output signal to activate xegregating unit and interruptive current.
